Scrub looking to start at ~$150

I'm looking to start at ~$150 I know very little. Looking for any helpful buying advice. Is buying used a legit thing? I've seen the Antminer s3+ at $150 which would take 147 day to break even with free power and no power supply. I've looked around the Reddit and found very little that would be helpful recently. Thanks

How can I know more about bitcoin mining and how can I start if I have free electricity?

I have free electricity in my university. Unless I am taking down the whole university network, nobody cares what I use.

So, how can I get started mining for cheap? What do I have to buy?

I am not looking to make a lot of money, but if I earn a little something and learn more about bitcoin on the way, it will be a win in my book.

Please help a noob out!

Hey guys (This is a refferal text) for Eobot.


So I just wanted to mention something EOBOT some may not have heard about. Do you have old mining gear collecting dust and looking to start mining again? well at Eobot you can mine LTC and those other pesky coins that require non-sha 256 miners. Yes I did say mine LTC and others, how it works is when you connect your miner to Eobot you will mine BTC instead and Eobot will covert your earnings into the coin you selected to mine.If you find this interesting and like to try it, please click my link, sign up. If you need advice, ask for me, name is Neltharionz on chat. If I am not there, most the time I am, you can ask one of the golden shield mods.My link, http://bit.ly/1OB6dLs via /r/CryptoCurrency http://bit.ly/1NETElb

Bitcoin dev IRC meeting in layman's terms (2015-11-26)

Once again my attempt to summarize and explain the weekly bitcoin developer meeting in layman's terms.
Link to last weeks summarization
Note that I crosspost this to Voat, bitcoin.com and the bitcoin-discuss mailing list every week.

Disclaimer

Please bear in mind I'm not a developer and I'd have problems coding "hello world!", so some things might be incorrect or plain wrong.
Like any other write-up it likely contains personal biases, although I try to stay as neutral as I can.
There are no decisions being made in these meetings, so if I say "everyone agrees" this means everyone present in the meeting, that's not consensus, but since a fair amount of devs are present it's a good representation.
The dev IRC and mailinglist are for bitcoin development purposes. If you have not contributed actual code to a bitcoin-implementation, this is probably not the place you want to reach out to. There are many places to discuss things that the developers read, including this sub-reddit.

link to this week logs
Meeting minutes by meetbot

Main topics discussed where:

CLTV activation
BIP68/BIP112 implementation
Replace-by-fee

Short topics/notes

It was an American holiday (thanksgiving), so there weren't a lot of people in the meeting, which started later as well.

Personal note: My weekly posts are being read by more people than I ever anticipated and people are expecting these to come weekly.
Next year starting Mid-February I'll be on vacation for a month, so that's 4 or 5 meetings I won't be able to do.
If there's anyone who's up for the challenge to take over during those weeks (or maybe just 1 week and share the load with others) feel free to pm me.
I'm announcing well in advance, so there's more chance to find someone and to not make this a last minute thing.
I'd prefer someone who doesn't work in the bitcoin space (coding), as I much rather have people work on the future of money instead of enlightening us noobs :)

CLTV activation

  • background

CheckLockTimeVerify (CLTV) aka "how you thought nLockTime worked before you actually tried to use it" aka OP_HODL.

  • meeting comments

It's plausible the CLTV softfork will activate within just a few weeks, as everyone but a few big miners have adopted it.
About 20% of the nodes currently run CLTV-supporting versions. The negative effect of not upgrading is a degraded validation (SPV).

  • meeting conclusion

Do a social media reminder to upgrade nodes to v0.11.2/v0.10.4

BIP68/BIP112 implementation

  • background

BIP 68 Consensus-enforced transaction replacement signaled via sequence numbers , and current implementation.
BIP 112 CHECKSEQUENCEVERIFY, and current implementation.
In short: BIP 68 changes the meaning of the sequence number field to a relative locktime. BIP 112 makes that field accessible to the bitcoin scripting system.

  • meeting comments

The BIP68 and BIP112 texts have been updated to match the implementations.
There's been a call and discussion to rename CHECKSEQUENCEVERIFY on the mailinglist.
btcdrak wants both pull-requests to be merged soon, others feel more hesitant as people seem to only recently started looking at it seriously.

  • meeting conclusion

Merge updated BIP-texts

Replace-by-fee

  • background

Currently when a node sees a transaction that spends the same output it ignores it. With replace-by-fee it replaces the current transaction in the mempool if it has a higher fee.
This allows for things like spending "stuck" transactions, adding more recipients to a transaction in order to prevent chaining, etc.

Since there are people that accept 0-confirmation transactions and this would make it extremely easy to double spend them, this is made opt-in.
The sender can choose to opt-in to replace-by-fee by changing the nSequence field of all inputs.
This is a mempool policy for the upcoming 0.12 release. There's a good FAQ-ish post on reddit about it.

  • meeting comments

petertodd ran some tests with the mempool limiter turned way down and saw no issues.
It should be technically easy to merge first-seen-safe and full-unconditional as options if there's people who want to write it in.

  • meeting conclusion

test and ACK replace-by-fee (Has been merged meanwhile).

Before the end of 2016, a countries central bank will officially add bitcoin to their basket of reserve assets. Inevitability in action.

In the same way, and for the same reasons as it is smart for an individual citizen to hold a small amount of bitcoin. It is more so the case for central banks to hold a small amount as part of their reserve assets.

The same phenonemon that naturally took place over the past 5 years with individuals is about to take place with central banks asset reserves. Once the first central bank makes the move, the game is on, and what central bank on the planet would want to risk getting left behind on the train that could completely destroy their countries balance sheets if it succeeds.

Kudos Barbados! Lead the charge!

Community-Currency


http://bit.ly/1IjRmpn community currency template with zero reserve mutual credit and adjustable parametersPurposeThis is not intended to be a global currency. It is intended to become an ecosystem of community currencies using this template, each of them with different parameters according to the needs of each community.The type of community we mean is local communities (for example a municipality) or communities with charitable, service, participatory or empowering orientation, that run mixed economies with free market combined with community public budget and public redistributive works. Examples can be local authorities, social movements associations, social economy businesses, workers unions, etc. It includes therefore an (optional) taxation function. Each community is supposed to name their currency with a different name.Currency Governance and monetary decission processWe decouple the contract running the decission process in a supposed DAO and the currency contract running the monetary mechanics. The DAO may use whatever more or less traditional or more or less innovative democracy to take decissions.The community is supposed to be managed by a DAO at ethereum or outside ethereum, or just run by a DAO using handwritten notebooks or any eGovernance software. The currency contract does not cover how the DAO is managed, the votings and decision mechanisms.Once the DAO has taken the main monetary decissions it passes the wished parameters to the currency contract through the two accounts allowed to change the settings of the currency: the treasury account and the community account. At creating the currency contract you may set who they are.The currency desing presumes that all monetary decissions of the community are implemented through two trusted accounts: * the treasury account. Creates the currency, sets the basic parameters and deploys it to the blockchain. It can mint and assign amounts of CCUs (Community Currency Units). * the community account. Admits or kickouts members. It can mint and assign amounts of Reputation. Users making a transfer can be anybody having an ethereum account. Members, additionally, can authorize credits to other members. Anybody, including Members, may have different ethereum accounts. The community is supposed to have external mechanisms to establish the identity of a person, and therefore establish which of his accounts this person prefers to use as the unique account as member.BackgroundWhat the hell is p2p credit at DESPERADOS THEORY blogMoneda con pagos y creditos p2p sin reserva at DESPERADOS THEORY blogApuntes sobre la soberania monetaria at Instituto de la Moneda SocialThe design has been strongly inspired on the paper Notas para una propuesta de dinero-crédito descentralizado y basado en la reputación presented at the III Conferencia Internacional de Monedas Complementarias, 28 de octubre de 2015 Salvador de Bahía. The paper reflects the experience of the complementary currency EUROCAT in Catalunya.It builds as well on the analysis made by the EU/FP7 project [D-CENT: Freecoin Toolchain Design and application to Pilots](www.dcentproject.eu) about the funcional requirements of the EUROCAT currency: Design of Social Digital CurrencyGeneralThe currency is supposed to be used within a community. Nevertheless, the currency can be used by anybody having an ethereum account to perform standard payment transactions. Whith regards payments it works as any other free market monetary token. Nevertheless, anybody using the currency pays a VAT for every transaction to the community, but no other taxes.Within the community, the members have additional obligations and benefits. They can be endorsed with Trust by peer members to get credit lines.p2p CreditsMembers have a Reputation as "Money Lenders". Members can authorise a p2p Credit to another member, with a deadline. Its up to the Money Lender to investigate the borrowers solvency. No algorithm is provided within the currency contract to analyze the solvency. Just an activity indicator.Once the credit is approved the system generates the necessary Community Currency Units and adds them to the CCUs balance of the borrower. The Money Lender pays with a reputation cost measured in endorsed Units of Trust. The Units of Trust needed to endorse the credit is proportional to the amount and the time of the credit.When the deadline is over: * if the credit has been returned, and the balance of the borrower is again positive, the Money Lender gets back the Reputation Cost and a reward in Reputation. In the future he will be able to authorize larger credits. * if the credit has not been returned, and the balance of the borrower is still negative, the Money Lender loses the Reputation Cost and a fine in Reputation. In the future he will be able to authorize only smaller credits. The borrower gets the account blocked until the debt is covered by future incomes. The Community has the option to kick this member out.Adjustable Parameterstreasury; the address of the treasury of the DAO.

Please help! I'm new to Bitcoin, and i'd like advice on how my family can use it to avoid using Western Union!

We live in the US and my sister lives in Israel. I'm looking for the simplest way that we can send/ she can receive money. She's not terribly tech savvy and my parents are not tech savvy at all, so please keep that in mind. Ideally, i'd like to be able to easily convert dollars into Bitcoin to send to her and then have her be able to convert the Bitcoin into shekels.

Before the end of 2016, a countries central bank will officially add bitcoin to their basket of reserve assets. Inevitability in action.


In the same way, and for the same reasons as it is smart for an individual citizen to hold a small amount of bitcoin. It is more so the case for central banks to hold a small amount as part of their reserve assets.The same phenonemon that naturally took place over the past 5 years with individuals is about to take place with central banks asset reserves. Once the first central bank makes the move, the game is on, and what central bank on the planet would want to risk getting left behind on the train that could completely destroy their countries balance sheets if it succeeds.Kudos Barbados!

/r/Bitcoin FAQ - Newcomers please read


Welcome to the /r/Bitcoin Sticky FAQMaybe you're here because you've received a tip on social media, or maybe you've just been hearing a lot recently about Bitcoin and are wondering what the big deal is? The following videos are a good starting point for understanding how bitcoin works and a little bit about its long term potential:Video 1: What Is Bitcoin & Why Should You Care?Video 2: The real value of bitcoin and crypto currency technologyVideo 3: Bitcoin Is Independent MoneyVideo 4: Bitcoin 101 - Balaji SrinivasanFor lots of additional video resources check out the videos wiki page or /r/BitcoinTV . Peer-reviewed, research papers can be found here and here. Developer resources can be found hereWhere can I buy bitcoins?You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank account. A good list of exchanges sorted by region can be found on the exchanges wiki here.Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Here are a couple useful sites [bitkoin.io, preev.com] that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".Securing your bitcoinsWith bitcoin you can "be your own bank" and personally secure your bitcoins OR you can use established companies which have secured wallets where they hold the bitcoins for you and provide insurance.If you prefer to let bitcoin banks manage your coins, try Coinbase or Circle.If you prefer to "be your own bank" and have direct control over your coins without having to use a trusted third party, there are many software wallet options here and here. If you prefer easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor, Ledger, Case Wallet, or KeepKey is recommended.Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access.

Purse.io and Amazon Account Shutdown


A short note to say that the person who was selling to me on Purse.io messaged me to say that their account was shutdown by Amazon. I still received the goods. So that is 1 out of 6 orders that I've made.I don't mean to attack Purse as I think there is still a lack of evidence as to whether they are a legitimate business or are accidently promoting credit card fraud.It would be interesting if Purse revealed how many of their sellers have lost their Amazon account. Would Purse know this information? via /r/Bitcoin http://bit.ly/1NkE4cn

Stuck transactions

EDIT: The Bitcoin network is currently under a sophisticated DoS attack using the "fake sigOp" method...

Some weird shit is going on right now: mempool size is above 10 MB total, with a total size of transactions paying at least the default recommended fee rate (10 satoshi/byte) being 8.5 MB. (Numbers from here). So there is definitely enough fee-paying transaction to fill several blocks with.

However, most blocks are far from being full, they do not even reach arbitrary limits set by miners. For example, you can see block #385917, mined by a KnCminer, having size 912 KB, and the next block #385918 is only 487 KB. So we see that KnCminer is OK with mining blocks as big as 912 KB, but found only 487 KB of worthy transactions.

Thus we can conclude that some anti-spam filtration measures are on, but what are they?

I think we might benefit if miners state the policies they are using, as it gives wallet developers a chance to change the way they make transactions, or at least warn users if transaction won't be confirmed soon

I just got a transaction confirmed after 4 hours of waiting. It wasn't a low-fee transaction: it paid about 20 satoshi per byte, which is twice the default fee rate. I think I know why it was delayed: it had an output which is only 3400 satoshi, which is only slightly above dust threshold, perhaps it made transaction look spam-like.

It's frustrating that miners' policy is so opaque. Let's look at block #385927, which is mined by F2Pool. It is 340 KB in size, which is smaller than other blocks recently mined by F2Pool, so we know it didn't reach the block size F2Pool set. No block explorers I'm aware of show transaction fee distribution for a specific block, so we have to do this manually. However, we can take advantage of the fact that Bitcoin Core sorts transactions by fee rate, thus if F2Pool uses block constructor based on it we will see this pattern.

5 of the last 7 transactions in the block pay almost exactly 20 satoshi per byte, so this seems to be a cut-off rate. The last two pay less than that rate, however, they coalesce many outputs, so it might be a result of prioritization.

The question I have is why do we have to learn about it through guesswork, aren't miners themselves interested in Bitcoin being a reliable payment system?

It's hard to figure out what the fuck they want from us even using fairly sophisticated statistical tools.

Who uses 0-conf transactions?

Honest question, there it a lot of talk about how opt-in replace by fee breaks 0-conf transactions.

I have always thought that no one usages 0-conf transactions anyway because they are not safe but there seems to be a lot of outrage about it. All the exchanges/services I use use between 3-6 confirmations so yeah.

Who uses 0-conf transactions? If I could get a few links I would understand the outrage better.
