NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

Mining and Dogecoin - Some FAQs

Hey shibes,
I see a lot of posts about mining lately and questions about the core wallet and how to mine with it, so here are some facts!
Feel free to add information to that thread or correct me if I did any mistake.

You downloaded the core wallet

Great! After a decade it probably synced and now you are wondering how to get coins? Bad news: You don't get coins by running your wallet, even running it as a full node. Check what a full node is here.
Maybe you thought so, because you saw a very old screenshot of a wallet, like this (Version 1.2). This version had a "Dig" tab where you can enter your mining configuration. The current version doesn't have this anymore, probably because it doesn't make sense anymore.

You downloaded a GPU/CPU miner

Nice! You did it, even your antivirus system probably went postal and you started covering all your webcams... But here is the bad news again: Since people are using ASIC miners, you just can't compete with your CPU hardware anymore. Even with your more advanced GPU you will have a hard time. The hashrate is too high for a desktop PC to compete with them. The blocks should be mined every 1 minute (or so) and that's causing the difficulty to go up - and we are out... So definitly check what is your hashrate while you are mining, you would need about 1.5 MH/s to make 1 Doge in 24 hours!

Mining Doge

Let us start with a quote:
"Dogecoin Core 1.8 introduces AuxPoW from block 371,337. AuxPoW is a technology which enables miners to submit work done while mining other coins, as work on the Dogecoin block chain."
- langerhans
What does this mean? You could waste your hashrate only on the Dogecoin chain, probably find never a block, but when, you only receive about 10.000 Dogecoins, currently worth about $25. Or you could apply your hashrate to LTC and Doge (and probably even more) at the same time. Your change of solving the block (finding the nonce) is your hashrate divided by the hashrat in sum - and this is about the same for Doge and LTC. This means you will always want to submit your work to all chains available!

Mining solo versus pool

So let's face it - mining solo won't get you anywhere, so let's mine on a pool! If you have a really bad Hashrate, please consider that: Often you need about $1 or $2 worth of crypto to receive a payout (without fees). This means, you have to get there. With 100 MH/s on prohashing, it takes about 6 days, running 24/7 to get to that threshold. Now you can do the math... 1 MH/s = 1000 KH/s, if you are below 1 MH/s, you probably won't have fun.

Buying an ASIC

You found an old BTC USB-miner with 24 GH/s (1 GH/s = 1000 MH/s) for $80 bucks - next stop lambo!? Sorry, bad news again, this hashrate is for SHA-256! If you want to mine LTC/Doge you will need a miner using scrypt with quite lower numbers on the hashrate per second, so don't fall for that. Often when you have a big miner (= also loud), you get more Hashrate per $ spent on the miner, but most will still run on a operational loss, because the electricity is too expensive and the miners will be outdated soon again. Leading me to my next point...

Making profit

You won't make money running your miner. Just do the math: What if you would have bougth a miner 1 year ago? Substract costs for electricity and then compare to: What if you just have bought coins. In most cases you would have a greater profit by just buying coins, maybe even with a "stable" coin like Doges.

Cloud Mining

Okay, this was a lot of text and you are still on the hook? Maybe you are desperated enough to invest in some cloud mining contract... But this isn't a good idea either, because most of such contracts are scams based on a ponzi scheme. You often can spot them easy, because they guarantee way to high profits, or they fake payouts that never happened, etc.
Just a thought: If someone in a subway says to you: Give me $1 and lets meet in one year, right here and I give you $54,211,841, you wouldn't trust him and if some mining contract says they will give you 5% a day it is basically the same.
Also rember the merged mining part. Nobody would offer you to mine Doges, they would offer you to buy a hashrate for scrypt that will apply on multiple chains.

Alternative coins

Maybe try to mine a coin where you don't have ASICs yet, like Monero and exchange them to Doge. If somebody already tried this - feel free to add your thoughts!

Folding at Home (Doge)

Some people say folding at home (FAH - https://www.dogecoinfah.com/) still the best. I just installed the tool and it says I would make 69.852 points a day, running on medium power what equates to 8 Doges. It is easy, it was fun, but it isn't much.
Thanks for reading

I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!

Requirements:
1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does.
**Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc*
So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though.
After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there.
Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly).
I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01
Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!!
-----How To Do This Yourself:
Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money.
Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses.
Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!)
Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!!

I have a Bitcoin Core Wallet from 2013.

So, from around 2010 to 2014 I used to mess around with mining Bitcoin. I started with CPU mining then bought a dozen of those usb asic miners then acquired a couple blade miners. My backup was to have multiple copies of my Core wallet so I wouldn't lose the coins. My failure was to keep multiple copies of the password. I used KeePass to store my password. Long story short, the KeePass database appears to be lost forever. I only know that the password is 32 characters long. By examining passwords generated by the software I can assume that it only contains no more than 3 of each characters and no two characters repeat simultaneously. It could contain upper case, lower case, and special characters.
With my video card I can only brute force 5000 passwords per second. At today's bitcoin price it is not practical to invest in more computing power but someday for my kids it could be worth it.
Right now it is just a project I am working on because these challenges intrigue me. I assume with a 12 GPU mining rig I could get more than 60,000 passwords per second but it would still be a matter of luck to crack it before I die.
...and go

Decred Journal – September 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link).

Development

Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures.
dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd.
Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome.
Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules.
Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd.
dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets.
Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue)
Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing.
Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged.
Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing.
A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning.
Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store.
iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.".
Nearest goal is to make the app crash free.
Both mobile apps received new design themes.
dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.".
Up next is supporting dynamic page widths site wide and deploying new visual blocks home page.
Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One).
Ticket splitting: updated to use Go modules and added simnet support, several fixes.
docs: beginner's guide overhaul, multiple fixes and cleanups.
decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet.
@Richard-Red is building a curated list of Decred-related GitHub repositories.
Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus!
Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate.
Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply.
Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.

ASICs

Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example.
A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1.
Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.

Integrations

Meet our 17th voting service provider: decredvoting.com. It is operated by @david, has 2% fee and supports ticket splitting. Reddit thread is here.
For a historical note, the first VSP to support ticket splitting was decredbrasil.com:
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks.
Three more wallets integrated Decred in September:
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets.
Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.

Adoption

The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.

Marketing

Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed.
Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate. (@Dustorf)

Events

Attended:
Upcoming:
We'll begin shortly reviewing conferences and events planned for the first half of 2019. Highlights are sure to include The North American Bitcoin Conference in Miami (Jan 16-18) and Consensus in NYC (May 14-16). If you have suggestions of events or conferences Decred should attend, please share them in #event_planning. In 2019, we would like to expand our presence in Europe, Asia, and South America, and we're looking for community members to help identify and staff those events. (@Dustorf)

Markets

In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August.
As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx)
Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.

Circle introduced USDC markets on Poloniex: "USDC is a fully collateralized US dollar stablecoin using the ERC-20 standard that provides detailed financial and operational transparency, operates within the regulated framework of US money transmission laws, and is reinforced by established banking partners and auditors.".
Coinbase announced new asset listing process and is accepting submissions on their listing portal. (decred)
The New York State Office of the Attorney General posted a study of 13 exchanges that contains many insights.
A critical vulnerability was discovered and fixed in Bitcoin Core. Few days later a full disclosure was posted revealing the severity of the bug. In a bitcointalk thread btcd was called 'amateur' despite not being vulnerable, and some Core developers voiced their concerns about multiple implementations. The Bitcoin Unlimited developer who found the bug shared his perspective in a blog post. Decred's vision so far is that more full node implementations is a strength, just like for any Internet protocol.

A question

Can someone explain bit coin mining? I'm interested in getting started.

Questions about starting using NiceHash Miner 2

Hi,
I am looking into mining cryptocurrency right now because i am interested. The recent gain of value in bitcoin hit my attention like probably everyone here :-)
I have heard of methods to mine especially with NiceHash Miner 2 (using computers, easy way) and an ASIC device such Antminer S7 (Look advanced to me). I already know there is a cost in electricity and such. However there are parts missing from my research and the whole puzzle..
My goal is not to make a tons of cash, i just want to explore the world of cryptocurrency and if possible get back my investment. I know there is an hardware investment but that not a problem for me especially since i might need a new computer anyway, however i might prefer to go the ASIC way if its better and that why i am here.
I have some questions...
1- Do the ASIC device such Antminer S7 do exactly the same thing that NiceHash Miner 2 ? Can Antminer S7 mine other cryptocurrencies than Bitcoin ?
2- There is a calculator on NiceHash Miner 2 website. How much this thing is accurate ? Do you really can make a profit based on this calculator numbers ?
3- I keep earing you get less profits if the difficulty raise. The difficulty will raise over time. What this really mean exactly ? In my understanding, NiceHash seem to mine from most profitable cryptocurrencies. Do that only affect Bitcoins or this can also affect other cyptocurrencies ? Do that effect is mitigated using NiceHash ?
4- Question about the wallet. How easy it is to convert the crypto currency into real cash ?
5- For storage do you recommand using a physical USB device instead ? Do cryptocurrencies take a lots of place or bandwidth ?
6- Knowing i need a new computer soon... should i invest in a new computer to mine using NiceHash Miner 2 in order to buy back my investment in a year ? or should i try invest in a S7 Antminer ? I could aswell just invest in bitcoin however i am not so sure that would be fun or the profit would be better in the long run. From your experience so far, which way should i try ?
Thanks a lots!

What is Bitcoin?
Bitcoin is an experimental system of transfer and verification of property based on a network of peer to peer without any central authority.
The initial application and the main innovation of the Bitcoin network is a system of digital currency decentralized unit of account is bitcoin.
Bitcoin works with software and a protocol that allows participants to issue bitcoins and manage transactions in a collective and automatic way. As a free Protocol (open source), it also allows interoperability of software and services that use it. As a currency bitcoin is both a medium of payment and a store of value.
Bitcoin is designed to self-regulate. The limited inflation of the Bitcoin system is distributed homogeneously by computing the network power, and will be limited to 21 million divisible units up to the eighth decimal place. The functioning of the Exchange is secured by a general organization that everyone can examine, because everything is public: the basic protocols, cryptographic algorithms, programs making them operational, the data of accounts and discussions of the developers.
The possession of bitcoins is materialized by a sequence of numbers and letters that make up a virtual key allowing the expenditure of bitcoins associated with him on the registry. A person may hold several key compiled in a 'Bitcoin Wallet ', 'Keychain' web, software or hardware which allows access to the network in order to make transactions. Key to check the balance in bitcoins and public keys to receive payments. It contains also (often encrypted way) the private key associated with the public key. These private keys must remain secret, because their owner can spend bitcoins associated with them on the register. All support (keyrings) agrees to maintain the sequence of symbols constituting your keychain: paper, USB, memory stick, etc. With appropriate software, you can manage your assets on your computer or your phone.
Bitcoin on an account, to either a holder of bitcoins in has given you, for example in Exchange for property, either go through an Exchange platform that converts conventional currencies in bitcoins, is earned by participating in the operations of collective control of the currency.
The sources of Bitcoin codes have been released under an open source license MIT which allows to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software, subject to insert a copyright notice into all copies.
Bitcoin creator, Satoshi Nakamoto
What is the Mining of bitcoin?
Technical details :
During mining, your computer performs cryptographic hashes (two successive SHA256) on what is called a header block. For each new hash, mining software uses a different random number that called Nuncio. According to the content of the block and the nonce value typically used to express the current target. This number is called the difficulty of mining. The difficulty of mining is calculated by comparing how much it is difficult to generate a block compared to the first created block. This means that a difficulty of 70000 is 70000 times more effort that it took to Satoshi Nakamoto to generate the first block. Where mining was much slower and poorly optimized.
The difficulty changes each 2016 blocks. The network tries to assign the difficulty in such a way that global computing power takes exactly 14 days to generate 2016 blocks. That's why the difficulty increases along with the power of the network.
Material :
In the beginning, mining with a processor (CPU) was the only way to undermine bitcoins. (GPU) graphics cards have possibly replaced the CPU due to their nature, which allowed an increase between 50 x to 100 x in computing power by using less electricity by megahash compared to a CPU.
Although any modern GPU can be used to make the mining, the brand AMD GPU architecture has proved to be far superior to nVidia to undermine bitcoins and the ATI Radeon HD 5870 card was the most economical for a time.
For a more complete list of graphics cards and their performance, see Wiki Bitcoin: comparison of mining equipment
In the same way that transition CPU to GPU, the world of mining has evolved into the use of the Field Programmable Gate Arrays (FPGA) as a mining platform. Although FPGAs did not offer an increase of 50 x to 100 x speed of calculation as the transition from CPU to GPU, they offered a better energy efficiency.
A typical HD/s 600 graphics card consumes about 400w of power, while a typical FPGA device can offer a rate of hash of 826 MH/s to 80w of power consumption, a gain of 5 x more calculations for the same energy power. Since energy efficiency is a key factor in the profitability of mining, it was an important step for the GPU to FPGA migration for many people.
The world of the mining of bitcoin is now migrating to the Application Specific Integrated Circuit (ASIC). An ASIC is a chip designed specifically to accomplish a single task. Unlike FPGAs, an ASIC is unable to be reprogrammed for other tasks. An ASIC designed to undermine bitcoins cannot and will not do anything else than to undermine bitcoins.
The stiffness of an ASIC allows us to offer an increase of 100 x computing power while reducing power consumption compared to all other technologies. For example, a classic device to offer 60 GH/s (1 hashes equals 1000 Megahash. 1GH/s = 1000 Mh/s) while consuming 60w of electricity. Compared to the GPU, it is an increase in computing power of 100 x and a reduction of power consumption by a factor of 7.
Unlike the generations of technologies that have preceded the ASIC, ASIC is the "end of the line" when we talk about important technology change. The CPUs have been replaced by the GPUs, themselves replaced by FPGAs that were replaced by ASICs.
There is nothing that can replace the ASICs now or in the immediate future. There will be technological refinements in ASIC products, and improvements in energy efficiency, but nothing that may match increased from 50 x to 100 x the computing power or a 7 x reduction in power consumption compared with the previous technology.
Which means that the energy efficiency of an ASIC device is the only important factor of all product ASIC, since the estimated lifetime of an ASIC device is superior to the entire history of the mining of bitcoin. It is conceivable that a purchased ASIC device today is still in operation in two years if the unit still offers a profitable enough economic to keep power consumption. The profitability of mining is also determined by the value of bitcoin but in all cases, more a device has a good energy efficiency, it is profitable.
Software :
There are two ways to make mining: by yourself or as part of a team (a pool). If you are mining for yourself, you must install the Bitcoin software and configure it to JSON-RPC (see: run Bitcoin). The other option is to join a pool. There are multiple available pools. With a pool, the profit generated by any block generated by a member of the team is split between all members of the team. The advantage of joining a team is to increase the frequency and stability of earnings (this is called reduce the variance) but gains will be lower. In the end, you will earn the same amount with the two approaches. Undermine solo allows you to receive earnings huge but very infrequent, while miner with a pool can offer you small stable and steady gains.
Once you have your software configured or that you have joined a pool, the next step is to configure the mining software. The software the most populare for ASIC/FPGA/GPU currently is CGminer or a derivative designed specifically for FPGAS and ASICs, BFGMiner.
If you want a quick overview of mining without install any software, try Bitcoin Plus, a Bitcoin minor running in your browser with your CPU. It is not profitable to make serious mining, but it is a good demonstration of the principle of the mining team.

Question about mining Ethereum.

TL,DR: I am mining on ethpool.org (Switched to Ethermine.org), what shows up there doesn’t show up in my wallet and I don’t know why. Is there something I am missing?
 
So I have just spent the weekend trying to successfully mine Eth. I am using the latest Claymore mining software (Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v7.4) , mining on ethpool.org, with the Mist wallet (0.8.7) geth (1.5.3). Having left the setup running for most of 3 days, what shows up on the ethpool.org stats page, never shows up in the Mist wallet and I don’t understand what is causing that disconnect. I do have some long running experience with mining Bitcoins with both GPUs and ASICs (Still running 2 cute USB ASICS just for fun). I am not trying to make money at this time, though I wanted to upgrade my graphics card anyway so I figured if I could mine some Eth while before PoS happens (maybe pay off the card) that’s cool too. My process is the following:
Starting geth from command line using geth.exe --cache=2048 --jitvm --maxpeers 100 –light to let it synch. Seems to work fine. I have previously tried using geth with –fast, to synch it seems to work fine that way as well.
Then I start Claymore with Start.bat containing the following.
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
EthDcrMiner64.exe -etha 0 -mode 1 -epool us1.ethpool.org:3333 -ewal 0x1846bB49FA4F0efE4BCe3F467c7b24c9490ea62f -epsw *
 
I then load up ethpool.org to monitor my mining progress and start Mist.
 
I am using the following hardware.
Intel i5-2600k, Asus P8Z68-V Gen3, 1.5TB hdd space on 2 drives. 16GB RAM. XFX Radeon R7 360 2GB (Clock: 1050MHz, Mem: 500MHz – Hynix DDR5) Driver version: Crimson 16.11.3 If you care, I am getting 3.9-4.4 Mh/s with Claymore. IIRC I was getting 2.something with other miners.
 
Known problems: Low number of peers. I am not using the recommended drivers. 2GB on video card is near size limit. Power is .11$ kw/h here.
 
Errors I have seen, but do not understand: contracts/release/release.go:134] Failed to retrieve current release: Missing trie node
 
Any questions? Any suggestions are welcome, thank you for taking the time to read this!

Guide For New Shibes

So it has become apparent to me from the constant questions on this subreddit that a lot of new miners/shibes need help, so I have decided to make a basic guide to most of the questions I see a lot here.
1) BTC - This means Bitcoin so If you see a miner that says BTC it does not work with dogecoin because dogecoin is Scrypt.
2) Scrypt - This is what dogecoin runs off of, or what your computeasic/gpu solves to support the network.
3) Asic - This stands for an application-specific integrated circuit, or in less confusing terms a miner dedicated completely to mining a particular type of coin such as dogecoin.
4) GPU Mining - Using a graphics card to mine crypto currencies.
5) CPU Mining - A slow and inefficient way of using your computers Central Processing Unit to mine crypto currencies.
6) Hash Rate - The rate at which you mine a crypto currency. The higher the better.
7) KH - This Means Kilo Hashes. 1KH = 1,000 Hashes a Second
8) MH - This Means Mega Hash - 1 MH = 1,000,000 hashes a second.
9) Should I buy an asic? - If you want to support the network yes. If you want to solely make money off of it No. Buy the coin if you want to make profit. This is my opinion, there is no one answer to this question.
10) Mining Pool - Pooled mining is a mining approach where multiple generating clients contribute to the generation of a block, and then split the block reward according the contributed processing power. Pooled mining effectively reduces the granularity of the block generation reward, spreading it out smoothly over time.
Tl/DR You Work with other miners to solve stuff faster making you money faster.
11) Mining Difficulty - How hard it is to solve the problems to generate dogecoin.
12) Do I need a fan? - Yes I cannot stress how important it is to properly cool your units. Make sure your units are always cool or else they might melt. Do not think you are safe just because you turn your ac up, but a fan.
13) What Mining Pool Should I Pick? - Here is a list of all of the pools Pick one that works for you.
14) What is a wallet? - This is where you store your dogecoin and where you can send and receive dogecoin.
15) What Wallet Should I get? - Online is convenient but not safe. Paper Is the Safest But Not convenient. Cold Storage is the mostly safe and somewhat convenient.
16) What is cold storage? - Basically putting your wallet on an offline device like a usb.
17) Can I mine on a mac? - Yes look here for more info.
18) Cloud Mining - A service you buy that mines for you. you pay for a certain amount of hashes, lets just say 10gh for an example, and the company/service mines you this amount for the time you bought. It is not profitable usually.
19) What Is a Raspberry Pi? - A small cheap computer that people use to run their miners on.
20) Watts - The measure of electricity.
21) Should I pre-order? No Never F%&$ing pre order, you will get scammed 99.9999% of the time.
22) Can I still mine? - Yes, you probably wont make money but you will support the doge community.
23) Linux - An operating system like windows that people use to run mining programs on.
24) If you Have an animal make sure to properly protect your mining rig from them. Wires from the machines make great chew toys.
25) How Do I calculate if im going to make money with my mining rig? - Use This mining Calculator This is also a very good calculator
26 What Mining Program Should I use? Windows: CG MINER Mac: Astroid Linux: CG Miner again
Goodluck mining I hope this helps. This Also Took A long time to make so support would be appreciated :)

My experience with Bitcoin: How I lost $5k and a potential profit for over $42k.

Happy Dec 1 everyone.
I can't sleep tonight and I have something to get off my chest, so story time.
I got into bitcoin soon after the crash in April. I was very interested in bitcoin and the way it worked and finally decided to buy when the price was around $105-$125 range. I spend $5k total and got around 42btc. That $5k was my life savings but I believed bitcoin was the future. At this time I was still working at my minimum wage job and barely getting by. I wanted a way out of my horrible existent. I wanted to go to school again but I was too worried about paying my bills or if I was going to make it the next month. I thought bitcoin was my way out. I was inspired by the stories of the people that "forgot" their wallet and all of a sudden they were tens or hundred-thousandaires.
While I was doing research I stumbled upon the bitcoin forums bitcointalk.org. I thought about mining bitcoin but didn't have the hardware. I don't have an awesome rig that can and I couldn't afford the asic units that butterfly labs were selling away. After a few weeks I learned that butterfly labs were not to be trusted and asicminer announced they we selling the usb miners. At this time the general consensus was that mining will never be profitable but I bought some anyway with the plans of reselling it. I got into bitcoin stocks because of asicminer. I have a few shares at the time and eventually got more and reinvested the dividends into the 1/100 asicminer. At this time things were looking up. I had a usb miner hashing away and asic miner was going up in price.
After a few weeks I sold my usb miners on ebay and got a good deal on it. I went over my breakeven point and had extra money. So I used the USD to buy more bitcoin with bitinstant. Bitinstant has a meltdown and didnt get my btc in time to reinvest in asicminer. The price shot up to 2.5btc a share and I missed out but it was ok. This is the high point of my life and experience with bitcoin. The dividends from asicminer was helping me pay some of my bills. I had a great investment going and I was richer than I had ever been. Bitcoin was my savior. Bitcoin was my answer. I got so excited about it I told my parents but they were disenchanted. I was met with "Why do you always daydream? Why can't you just go to school and get a real job? Imaginary money, fake money, scam." I'm not that smart so its hard for me to go to college but everyone keeps telling me you have to go to school to get a good job.
Well the next month came and ebay hit me with a 10% fee for successfully selling my stuff. I didn't know about the fee so I was caught off guard and now my bank account is in the negative. I didn't eat for the next few days while I was waiting for my bitcoins to turn into USD and transfer to my account.
I have been spending a lot of time lurking bitcointalk.org and there was news of these new start ups. BTCgarden and Labcoin. I was thinking I'll show my parents that I'm not daydreaming, I'm going to make it big and they won't be disappointed. So I sold all my asicminer shares and had around 90btc all together. I split between the two and when BTCgarden failed I dump the rest into Labcoin. Asicminer was falling in price at this time and I was glad I made it move. At the height of Labcoin I had over 150BTC. I thought I made it. I was happy. The next day burnside [stock exchange operator] announced he was going to close down his exchange and the price for everything plummeted. I didn't find out until a few days later when I was my stocks were worth 1/6 of what they worth. I was destroyed, I didn't know what to do and I was drinking the Labcoin cool-aid hard. I thought that its ok, the price will go back to IPO and I can sell. Months pass and I lost my job. I couldn't focus at work and I was really pissy. Now I'm sitting on useless Labcoin shares and joined with the group of people looking for a lawsuit, knowing full well I'll never get my money back. I lost my apartment last week and I had to go home with my parent (who are rubbing this shit in my face every chance they get. That is the reason why I moved out in the first place). I had the worst thanksgiving ever and I'm not looking forward for Christmas or the New Years. Its hard trying to find a job. I don't know what to do anymore. Its killing me that bitcoin is over $1k. If I had just kept it in my wallet and didn't touch it I would have over $40k now. Hindsight is a bitch.
Thanks for listening. I hope you guys have a better time with bitcoin.
TL;DR: This is not a bitcoin success story. Its a story about my highs and lows and ultimately my failure.

Raspberry Pi + ASIC defcoin mining guide

Want to get started mining defcoin with an ASIC and a Raspberry Pi? Does 360 KH/s of mining power sound appealing? Here’s how to do it.
https://pbs.twimg.com/media/Blpj8IvCcAEIStY.jpg
1) Hardware List
-Raspberry Pi Model B
--SD Card
--Micro USB power supply
--Ethernet cable
-Gridseed ASIC
--12V power supply (5.5mm/2.5mm barrel connector)
--USB to Mini USB data cable
The main component is the Gridseed ASIC, which will be doing the Scrypt calculations. The Raspberry Pi will be used as the controller for the ASIC, and will be doing the communication with the mining pool. If you’re not familiar with the term, an ASIC is an Application-Specific Integrated Circuit - basically a chip with a single purpose, like mining crypto currency. Using an ASIC will allow us to mine more efficiently than we would be able to with general purpose hardware.
The ASIC that I’m using is a “300+ KH/s Single Gridseed ASIC Miner”. It looks like a CPU heatsink with a fan attached. There is actually a circuit board with 5 ASIC chips sandwiched between two halves of this heatsink, and has a mini USB connector and a power connector sticking out the side. There are a few places where you can buy these. I bought mine at GAWMiners.com for $130. That was the lowest price that I could find, and I had a good experience buying from them. Use this link, and you can get $20 off of a $200 order (and give me some referral points :-)) GAWMiners. You can also find other vendors by searching for “Gridseed ASIC”. You’ll need a 12V power supply to power the ASIC, and a USB A to USB Mini B cable to connect the ASIC to the Raspberry Pi. I’m using a 60W power supply, which seems to be working fine for defcoin (Scrypt) mining. These ASICs can also mine Bitcoin at the same time, but you may need a beefier power supply if you want to do that.
The Raspberry Pi can be purchased at any number of places- Amazon, SparkFun, AdaFruit, etc. I’m using the Model B because I had one already, and also because it has a built in ethernet port that will make connecting to the internet easy. Make sure to get an SD Card and a micro USB power adapter to get the Pi up and running too.
2) Software
If you haven’t already, download the defcoin wallet from defcoin.org. If you want to do pooled mining, create an account for one of the defcoin pools, such as redbaron.us or whichever other pool you want to mine. Once you’ve created a pool account, make sure to create a worker too (for MPOS pools, that will be under My Account > My Workers). The password for your worker does not have to be the same as the password for your pool account (and it probably shouldn’t be).
Next, download the latest Raspbian image from raspberrypi.org/downloads/ and install the image to your SD card. Instructions for installing the image can be found here. If you are using the dd method on a Mac, make sure to use /dev/rdiskX instead of /dev/diskX - both will work, but rdiskX is much faster. Once you have the image installed, put the SD card in the Raspberry Pi, connect the Pi to your network, and connect the Pi to your micro USB power adapter to power it on. Next, SSH in to your Raspberry Pi with the default username and password pi/raspberry. I use nMap to find the IP address that has been assigned to my Pi. You can also use an HDMI display and a USB keyboard to log in instead of using SSH. After logging in for the first time, run through the wizard that comes up to configure your Raspberry Pi. The defaults are fine for most things, just make sure that you don’t skip the step to expand the filesystem to use the rest of your SD card. If you don’t expand the filesystem, there won’t be enough space for other software.
Once you have Raspbian installed, and have gotten through all of the first login setup stuff (which will likely end with a reboot), log back in to the Raspberry Pi with the pi user. From the command line, run sudo apt-get update sudo apt-get dist-upgrade
There are some stability issues with USB communication between the Raspberry Pi and the Gridseed ASIC. Enabling SLUB debugging seems to resolve this, at least well enough to prevent the Raspberry Pi from freezing every so often. Open the /boot/cmdline.txt file, and add the following text to the end of the line. Don’t add a new line, just add this to the end. You can use vi, nano, or whatever your favorite text editor is to do this.
slub_debug=FP 
Reboot the Raspberry Pi once you’ve added that flag to your /boot/cmdline.txt file.
sudo shutdown -r now 
Log back in with the pi user once the Raspberry Pi is finished rebooting.
The mining software that we’re going to use is a customized version of cgminer that has support for the Gridseed GC3355 chips that are used in our ASIC. There are a number of different mining programs out there, this is just what has been working the best for me so far. First, install git and dependencies needed to compile cgminer.
sudo apt-get install git build-essential libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake 
Next, clone the git repository for cgminer-gc3355
git clone https://github.com/dtbartle/cgminer-gc3355.git 
Next, we’ll build cgminer.
cd cgminer-gc3355 autoreconf -i ./configure --enable-scrypt --enable-gridseed make 
Once the make command finishes, we’re ready to run the mining software. You can also run make install if you want to install the software, but running it out of the build directory works just fine. Plug in the power supply for your ASIC, and connect the ASIC to it. Connect the USB cable to the ASIC and to your Raspberry Pi. Run the mining software by running the following command. The -o option specifies your pool URL, the -u option specifies your username and the workername that you set up for the pool, and the -p option is the password for your worker. There are a couple of options available that are specific to the gridseed ASICs, and those will be placed after --gridseed-options. The freq=850 option sets the clock frequency of the ASIC to 850 MHz. There are other clock options available, but 850 seems to be working best for me. I was getting hardware errors at 900, and a lower average hash rate. I am getting about 360 KH/s with the clock frequency set to 850.
sudo ./cgminer -o stratum+tcp://www.redbaron.us:3333 -u Username.Workername -p yourworkerpassword --gridseed-options freq=850 
This command needs to be run with sudo in order to access the USB hardware. You can also create another user specifically for mining, or grant the pi user the appropriate permissions if you don’t want to run cgminer as root. When you run this command, you should see output from cgminer showing that it is communicating with the mining pool, and something showing your hash rate. If you’ve gotten this far, and you’re seeing output from cgminer showing a hash rate, congratulations, you’re mining defcoins with your ASIC! There are just a couple more steps to do if you want to let your Raspberry Pi and ASIC continue mining without needing you to be logged in.
To keep cgminer running after I log out, I am using nohup. You could also use screen instead of nohup. Create a script (startMiner.sh) by running the following commands.
echo “nohup /home/pi/cgminer-gc3355/cgminer --real-quiet -o stratum+tcp://www.redbaron.us:3333 -u Username.Workername -p yourworkerpassword --gridseed-options freq=850 &” > /home/pi/startMiner.sh chmod a+x /home/pi/startMiner.sh 
If you run this command with sudo startMiner.sh, cgminer will run in the background, and will continue running after you log out. If you want to have this run when your Raspberry Pi boots, modify your /etc/rc.local script so that it executes this startMiner.sh script. Your /etc/rc.local file will end up looking like this:
# Print the IP address _IP=$(hostname -I) || true if [ "$_IP" ]; then printf "My IP address is %s\n" "$_IP" fi /home/pi/startMiner.sh exit 0 
That’s it! You should now have a Raspberry Pi controlling a defcoin mining ASIC, that starts mining as soon as it boots up. For more reading, check out some of the links below.

**Why I Am Mining Dogecoin**

I began seriously mining Dogecoin yesterday. I spent the last several days assembling and configuring a computer for this (among other uses). I developed a strong interest in digital currency in the last month, and have been gently wading into this exciting new world that we are all building together. I have a wife, children, and a day job, and have had an unsuccessful time explaining why I'm so interested in this, and why altcoins and Bitcoin are not a pyramid scam, a joke, etc.
Here, I hope to explain my personal reasons for choosing to spend time and money in Dogecoin mining, since it may be useful to others coming into digital currencies, as they are gaining more and more press and publicity lately with many articles in the mainstream press on Bitcoin, Coinye, etc.
Only a month ago, I began to notice that Bitcoin was really being mentioned a lot in the media. I had known about it for several years, but had assumed it would just go away. It never made sense to me (it does now!), but I didn't spend much time thinking about it. I figured, "after all, there's nothing backing it", and left it at that. Obviously, I knew nothing about currencies or monetary systems at the time, and neglected the fact that nothing tangible backs a USD either.
After hearing about the Dread Pirate Roberts / Silk Road bust, I was surprised to learn that Bitcoin was alive and had grown to such an impressive value (it was around $1,000 USD per 1 BTC at the time, as I recall). Later, I heard a longer story about Bitcoin on the radio (on NPR, I believe), and was further surprised that several legitimate, real-life businesses had started to accept Bitcoins. Now, I was hooked, and needed to learn more. By the end of December, I'd read enough about Bitcoin to know I wanted to participate, but wasn't comfortable speculating in it with real money.
I knew it wasn't going to be profitable, but in early January, I spent about $40 on a USB ASIC "Block Erupter" for Bitcoin mining. This runs at 334 MH/s (using Bitcoin's SHA-256 algorithm, not Dogecoin's scrypt algorithm). This has been sufficient to generate approximately $0.75 worth of Bitcoins over the last 2 weeks that I've been running it. It gave me something to play with, but was pathetic compared to what the professional miners were doing (measured in TH/s, tens of thousands of times faster than my capability). Reaching their levels required more specialized ASIC hardware (not just a single USB key-sized device).
The higher performing Bitcoin mining hardware was all backordered or available only from relatively unestablished companies that I would not want to send thousands of dollars for. Furthermore, the hardware seems to only really be usable for Bitcoin mining; it had no other obvious utility.
BUT, through cryptsy it was easily possible to convert other altcoins into BTC or vice-versa. Litecoin, Dogecoin, and others were mentioned in several mainstream news articles. Dogecoin was treated as a joke and novelty. However, on looking into it, along with several other altcoins, I decided it was more than serious.
Dogecoin:
Few or no other altcoins seemed to have all these properties to the same degree as Dogecoin. I started CPU-mining it immediately, lacking any GPU hardware in my house (I am not a gamer).
Even the modest CPU power in my home PCs (used for web surfing, primarily) was able to generate a little less than 1,000 DOGE per day (which was roughly $0.25 - $0.30 at the time). Not super-impressive, but enough to play with and check out the rest of the Dogecoin universe.
I became hooked. I decided that not only was this a fun thing to play with, but it was also potentially a very good investment. Not having much spare cash, not having a high risk tolerance, and not having any desire in being a "speculator", I decided that rather than convert USD to Dogecoin, I would build a more capable mining computer. I will share more details on this later, if there is interest.
Dogecoin mining on GPUs and CPUs is easy, and the cost of building a machine for this is very reasonable, considering that the machine has many other uses, including:
This is vastly superior to me, compared to investing the same amount of money in Bitcoin hardware, which is useless for anything else. Rather than speculating in Bitcoins, I decided there was no risk at all in building a computer with high-powered GPUs that would be useful for Dogecoin's scrypt-based altcoin mining, since even if it never made economic sense, I could use the system for many other things.
I had not built a PC in over 10 years, and would up spending about $2000. Since yesterday night, I am now mining Dogecoin at a consistent rate of 1.2 MH/s (my hardware can go to 1.6 MH/s, but the temperatures did not seem healthy to me, so I slowed it down while I study them).
This is extremely fun, and I'm proud to be contributing to the Dogecoin ecosystem.

Help with getting things to start mining scrypt currencies (using raspberry pi 2 , gridseed asic miner , & cgminer) . . .

Here's what I have & will be using (I already have the cables & power) :
raspberry pi 2 Gridseed ASIC Miner for Litecoin and Bitcoin Mining --- 4 of these cgminer
[ I followed this example for setting things up : https://www.reddit.com/defcoin/comments/23nvs1/raspberry_pi_asic_defcoin_mining_guide/ it is my understanding that any altcoin you wish to setup mining for , is done in this similar fashion ]
I want to do scrypt cryptocurrency mining , I just want to understand how this is done ....
( I know there's a lot of tutorials out there & great vids , and I've done a lot of reading on all this matter , but I can't seem to get things working right , please help / advise )
Questions:
  1. if I solo mine , what is the correct port # to use here (and is the below command formatted correctly more-or-less) :
sudo ./cgminer -o stratum+tcp:localhost:#### -u Username.Workername -p yourworkerpassword --gridseed-options freq=850
( I understand I need to create my own pool , a pool of 1 , is considered to be solo-mining , correct ? How do I do this ? )
  1. also , before I can solo-mine , I need to have downloaded & install the wallet for the cryptocurrency I am going to mine , correct ? And I understand there is some kind of Config files relevant that I should modify accordingly to set things up with my mining solo , right ? How is it done & where do I find this config files ??
  2. I tried connecting my 4 gridseed(s) to my raspberry pi 2 , via the 4 usb ports it has , but it seems like it can't handle the 4 of them , so I have to deal with only using 2 of the gridseed(s) connected to my raspberry pi 2 at a time .... does this seem right to you ? And so , what work around do I have for this poroblem , I want to use all 4 of these gridseeds connected to my raspberry pi 2 ,,, I'm guess a usb hub is needed for this right ?
THANKS IN ADVANCE FOR YOUR HELP AND GUIDANCE !!!

If anyone has a wallet printer! I have a request inside!

Hello /bitcoin! A little background for this request, I am currently a sophomore at university pursuing accounting. Ive followed Bitcoin for a while, had a few usb ASIC miners last year but sold to simply recover my expenses. Last year I took an Economics 100 with a really cool professor, it was a fun class and we even had discussions on Bitcoin (this was during the $1000 peak as well). He's always been intrigued by the phenomenon and likes to incorporate as much new and current information as he can into his course.
Fast forward to this year, I luckily managed to snag a spot in his Economics 210 course. During the first day, he set a bunch of different types of paper currency on the table at the front and asked what makes it valuable? No one in the class besides me even mentioned bitcoins and the proof of work. But it got me thinking, I should give him a paper wallet to add to the mix.
I talked to him about it and he loved the idea. So Im asking anyone on this sub who has a nice printer (I thought there was one that was able go print in nice color and have cool security codes and such like on today's USD)
I have 0.05 btc to put on the paper wallet and would be willing to pay for shipping and your time through Paypal or by some more btc (whichever floats your boat, I just need to buy some more then lol)
If anyone can help, it would be awesome and much appreciated!

J'ai acheté un mineur USB en Bitcoin à Saint Lazare

Après avoir beaucoup réfléchi à investir dans le minage, fait des calculs, observé le marché, lorgné du côté des BFL Jalapeno, et vu la difficulté monter en flèche, j'ai finalement sauté le pas aujourd'hui en achetant un Block Erupter ASIC Miner usb.
Je suis convaincu que nous vivons une révolution, et j'avais envie de posséder un petit bout de cette histoire de crypto devises.
Je fais donc un tour sur le net, localise quelques vendeurs, les contacte un par un pour finalement avoir une réponse: Monsieur Spam en a plusieurs, il les écoule à 15€ pour investir dans autre chose. Rendez-vous est pris en plein centre de Paris à midi.
Je dépose quelques bitcoins dans mon wallet android, et en route pour ma première transaction crypto devise contre objet tangible.
Mon vendeur est en place, nous papotons: développeurs tous les deux, lui s'est mis à miner sur CG il y a longtemps, cette époque bénie où l'on pouvait chauffer son appart en gagnant de l'argent à coup de dissipateurs thermiques :) Les temps changent, la donne est différente; nous sommes convaincus que bitcoin est là pour durer, au moins faire bouger les lignes.
Vient le moment de payer. Je sors mon smartphone, scanne le qr code affiché sur le sien, envoie 15 euros, et "DRING" ! La transaction est effectuée quasi-instantanément, les bitcoin sont dans son wallet. Je l'invite au prochain meetup et sur reddit, on se reverra peut être, c'est une petite communauté.
Ce qui est impressionnant, c'est que lors d'une transaction de personne à personne dans le monde réel, le processus est extrêmement fluide avec les appli smartphone. 3 clics et boum c'est bon. Easy as cash !
Je pars donc avec ma minuscule machine, et me prépare à miner n'importe quoi à l'aide de CryptoSwitcher et CoinChoose... peu importe le flacon, pourvu qu'on ait l'ivresse.
TLDR: j'ai acheté un ASIC avec des bitcoin et ça s'est super bien passé.

Looking into bitcoin mining

Im really interested in mining bitcoin but i want to know what you guys think my setup should be what i was thinking was getting a couple of asic usb block erupter and a powered usb hub with a fan and either use it with ny computer or a raspberry pi. I already have the rasppi. Should i just spend some money on a asic miner? What programs should i use (wallet and miner)

Withdrawing from my wallet as a novice.

I've been following Bitcoin for a year or so, keeping it in my feed, reading up on it etc. I got myself a wallet and did nothing with it for a long time, as I was never up on the technical side of things...I'm still not!
Then I used the faucet mines to see something actually go into my wallet, albeit tiny amounts, which became a strange habit when I was bored at work. A friend then lent me a USB ASIC miner which I also ran at work or at the library when I could (no electricity bills!).
So now I have something in the wallet, but I'd like to remove the entire contents into a offline/papebrain wallet. The entirety off transactions and wallets is a bit confusing still for me so if anyone could help understand how to pay all the contents out into the most secure version of an offline wallet then I would be most grateful!
I'd also like some help getting some coins into my Reddit account so I can start tipping!

I want to sell: Butterfly Labs 5 GH/s Jalapeño ASIC Bitcoin Miner
The price in BTC (includes shipping): 1 BTC to 134Z2Sv5B7UwUhoSxypaXGyjqHKWoTWUgv
I am willing to ship to: USA (others negotiable and not for free)
Images of my product: http://imgur.com/a/EcgZh
Proof of hardware and hash rate in images linked above. Note that trail off at end of graphs is from shutting down the miner purposefully.
I am the first owner, and I received this miner directly from Butterfly Labs less than 48 hours ago. I still have the original box, power supply, USB cable, and of course the miner.
After tinkering with it for a few hours I have successfully mined Bitcoins (BTC), Freicoin (FRC), and Zetacoin (ZET) using my MacBook Pro and the miner GUI Asteroid. Pretty cool stuff. I have a few fractions of BTC in my wallet now so I can say that, "I mined cryptocurrencies back when I was your age" to the grandkids one day.
Now that my curiosity is sated, I'd like to pass this ASIC on to another aspiring minetinkeregeek and let them have a go at it. I can offer help if you are running Mac OS X.
If you are in the Seattle, WA area I'll deliver in person and help you get it up and running.

The laws may change in the future.
Why does my "Total Cryptocurrency Value" go down? This is because that display is tied to the exchange rates on other websites. Also see this user generated YouTube video for more information: https://www.youtube.com/watch?v=GucqlMuIXMg
Are their any fees to join or monthly fees? No fees.
Do you speak Spanish/Russian/Chinese? No, only English, but Google Translator works well.
What are the maximums/minimums for withdrawing? There are no maximums. The minimums are small, see the withdraw page for details.
Where can I see the terms and conditions? Please click here for terms and conditions.
Where can I see the privacy policy? Please click here for privacy policy.
Are you hiring? We are always looking for quality talent. If you would like to contribute, then please send your cover letter and resume to [email protected].
Do you have a bug bounty program? Yes, we pay for bugs, so contact us for details or visit us at CrowdCurity.com and submit bugs there!
Do you perform off-chain transactions? No we do not. All cryptocurrencies are sent, usually including miner fees, and can be seen on the blockchain for that respective cryptocurrency. This helps secure the network, makes our transactions transparent, provides an easier way to debug and track down coins, and reduces the chance for fraud. An off-chain transaction would be like what Coinbase could do if both users are Coinbase users and they change coins from one email to another, mark it in the database, and Bitcoin is never actually sent from one wallet to another.
Why does my balance reset after refreshing the page or changing cryptocurrencies? The server updates every 60 seconds and the balances you see updating in real-time are performed with Javascript. If you change pages quickly, or choose a new cryptocurrency, then it will look like it is resetting. However nothign is lost, as whatever cryptocurrency it is set at when the server updates will get the past 60 seconds of mining results.
Help! My account was hacked and withdraws are being made? Eobot is a secure site and has never been compromised. If your account was hacked, then you should change your password, turn on 2FA, and turn on email notifications. There are many unscrupulous Bitcoin sites, and most likely, you used the same password on another site. Never re-use passwords!
Do you have any wallpapers? Yes, you can download wallpaper1 or wallpaper2. Feel free to send us your own creations.
What does Eobot stand for? We have heard everything, let us know your favorite, including: Earn Online Bot, Earn Online Bitcoins Online Tool, Earn Online By Our Tech.
Is this legal? We cannot provide legal advice; make sure cryptocurrencies are legal in your jurisdiction before continuing to use Eobot.
Cloud Mining Questions What are the Cloud Mining fees? For electricity and maintenance, we currently charge a fee of 65% for SHA-256 and 65% for Scrypt. These values will change as difficulty increases, exchange rates change, and newer ASICs come online. These fees are better than our competitors, for instance CEX.IO charges $0.105 per GHS, which is a 81% fee! While GAW charges a 96% fee at current prices!
How long are the Cloud Mining rentals and contracts? Prior to October 11 2014, GHS/KHS contracts had no expiration. Old contracts are not affected. New contracts and rentals, mined or purchased after October 11 2014, are now limited in term for 5 years going forward. See your History tab for expiration dates.
Can I sell my Cloud Mining? No, you cannot sell the cloud shares at this time. This is because we own the hardware and do not want to be stuck if everyone decides to sell at once.
Can I buy Cloud Mining with credit card/USD? Yes, but please keep in mind you cannot sell or convert the Cloud Mining.
Can I buy Cloud Mining with cryptocurrency? Yes, deposit the cryptocurrency and then convert it to your choice of Cloud Mining.
What are the maximums/minimums when making a credit card purchase to buy Cloud Mining? The minimum is 1.0 GHS and 10.0 KHS and there is no maximum at this time.
Can I buy a Cloud Mining that mines in Scrypt? You can use the Cloud Mining SHA-256 hashing power to mine other currencies by automatically converting them as you mine, but the earnings will still be tied to SHA-256/Bitcoin difficulty, not Scrypt/Litecoin difficulty.
What is the difference between Cloud Mining SHA-256 and Cloud Mining Scrypt? One is tied to the difficulty in mining SHA-256 cryptocurrency (Bitcoin) and the other is tied to the difficulty in mining Scrypt cryptocurrency (Litecoin). This means that if history is any indication of the future, then the Cloud Mining Scrypt won't decrease as fast as the Cloud Mining SHA-256.
What does 1 instance of Cloud Mining SHA-256 and Cloud Mining Scrypt equal? 1 of Cloud SHA-256 equates to 1.0 GHS of SHA-256 mining power, while 1 of Cloud Scrypt equates to 1 KHS of Scrypt mining power.
Can I change the pool that my Cloud mines on? No, you cannot; this may change in the future.
What hardware is behind the Cloud Mining? The hardware varies from custom ASICs to GPUs. The ASICs are behind the SHA-256 and the GPUs are behind the Scrypt.
Can I RDP (remote desktop) into my Cloud Mining? No, you cannot at this time; we will run the servers for you.
What is the Cloud Mining Pre-Order? These are the same as the other Cloud Mining, but they will start mining on a later date. For instance, a Cloud Mining Pre-Order October 2014 will start mining on October 1, 2014.
Software/Miner Questions Why is it stuck on "initializing...please wait 5 minutes"? We recently changed our Scrypt pool, so this messge will show and the stats and speed won't show under your account. See pool info page for more info.
Why does it show as a trojan/virus? This is a false-positive that many of the popular antivirus programs report. For now you can ignore it, or try another free antivirus, like Microsoft Security Essentials. Hackers use something similar programs to make money off of people's computers, so that is why it shows up as a virus.
Why does Chrome block the download as malicious? This is another false-positive. Simply, go to your Chrome settings, scroll to the bottom and click on "Show Advanced Settings". Go to the Privacy section and uncheck "Enable phishing and malware protection". You will only do this temporarily. Then proceed to download our software. Then return to your privacy settings and recheck Enable Phishing to further protect you.
Do you have a Mac or Linux version? Yes, see the Pool Info under the Account page.
How do I use cgminer? See this English PDF tutorial for cgminer, or Spanish version, created by one of our members, for a simple walk-through.
How can I increase the speed? Important to increase speed: The default cgminer settings do not include hardware specific flags, which you may find here in the Litecoin Mining Hardware Comparison. Failing to use the proper flags can result in performance decreases in excess of 50%.
What do the intensity settings relate to? This is the same as cgminer flag --intensity. Low is 11, normal is none, high is 15, very high is 17, extreme is 19.
Can I use one account for multiple computers on same IP address? Yes, it will add your speed/rates together, you can use as many computers as you want.
Can I connect to the pool manually, through cgminer or bfgminer? Yes, see the Pool Info under the Account page.
Do you use Bitcoin and Litecoin? Yes, we are the easiest miner to use with BTC and LTC and convert on the backend automatically.
What do you use on the backend? We use cgminer, bfgminer, pooler's CPU miner, and a variety of pools.
Can I mine any cryptocurrency? Yes, regardless if you use SHA-256 or Scrypt (BTC vs LTC mode), you can earn and mine any cryptocurrency.
Can I use an ASIC? Yes, simply choose the option and run as GPU mode. Devices that work with bfgminer will work, for instance USB Block Eruptors or Butterfly Labs ASICs. You can also contact us for pool information for other ASICs.
What is the best graphics card/computer to buy? Either use a high end ATI Radeon card, or buy one of the USB Block Eruptor devices on Ebay/Amazon or a similar online store.
What drivers do I need for USB mode? http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
Why doesn't GPU mode work? You may need to download the OpenCL drivers; get them from here: http://developer.nvidia.com/opencl
Where can I get the .NET framework? Try Windows Update, or use Microsoft Web Platform Installer.
Can I use a proxy server? Yes, edit intensity.txt and put the details in there, for example, add "--proxy=http://mycompany-http-proxy:8080"
Where can I download the software? Download from link here
Can I use custom flags/change intensity? Yes, you can put in whatever custom flags/parameters/arguments you want. Edit the "resources/intensity.txt" file. Put in whatever you want, like for GPU mode: "--intensity 12 --shaders 1024" or for CPU mode (number of threads): "-t 32"
