It was only a TXT File where i save the data and send the txid's in raw out.
Maybe anyway to see the QR-Codes again ? or find the File in Google Chrome Cache/Temp ?
So you replaced that text file that had the keys and QR codes? You should (a) describe exactly what you did and (b) you might be able to use a file recovery program depending on exactly how you replaced the file (e.g. opened it and pasted new contents in there vs saved over it vs dragged in trash and deleted). If you want hope of recovering it, you should stop using the computer right away so that the contents of the file have a smaller chance of being over-written.As far as a browser cache, where you running in private mode etc? Offline copy? Online? |

Hello,
when i download Bitcoin application, create wallet from within it, then i backup whole application folder to external drive.
Then i deposit some coins into wallet and after some time, primary hard drive is lost and so i restore old app backup from time i had no coins in the wallet.
Will that mean i lost money on the wallet? In which file is stored most important data that i want to backup and protect?
To add to what Lauda stated, it depends on what program and version. If you are running Bitcoin Core 0.13.0 or greater AND you haven't created a wallet using it before (e.g. this is the first time you are using it to receive bitcoins and didn't run earlier versions/keep the older wallet.dat file), it will create a HD wallet so, although you should back it up, you shouldn't have to worry about the 100 address issue as it is a HD wallet. |

Make sure you have backed up your wallet.dat file. If you have a password on your wallet then backup that data as well.
Step 1: Use a bootstrap file that has the blockchain downloaded till a specific date and replace that data with the one in the appdata/roaming/"btc-wallet" folder. Then you should resume downloading with a real advantage, you might only need to download something like 10% or less.
Another option is to just download Multibit and import your wallet.dat and password data. The blockchain syncing process on Multibit is pretty quick. If you are just sending quick transactions then forgetting about it then that software is pretty good.
If you want to be more secure then use Electrum like the user stated above.
Do not use a bootstrap file, that has been bad advice for nearly two years now. Syncing with bitcoin core is faster. Likewise, pretty much the rest of the message is bad advice too. Edit: waveaddict is applying for a sig campaign which generally pays by the post, not matter how accurate or inaccurate they are. |

Yes that's what i mean. I have an antminer s5 but i dont know how to set it up to 'get work' specified for myself rather than that of a pool.
I could use excel but practically is going to way to slow.
Any tips on set up or point me to a guide?
It seems you want to solo mine, threads like this have details and discussions, but this is a bit dated, if this is what you are asking about, there is info all over: https://bitcointalk.org/index.php?topic=496560.0You might consider checking out p2pool, because unless you are incredibly lucky, you won't solo mine a block, but p2pool is a distributed pool so you'll get rewards but not as part of a non distributed pool. Solo mining has been nearly impossible for 4+ years now. If you aren't talking about solo mining, I'm not sure what you are asking then. |

But i already Transfered all my BTC to this Acc
Can i anyhow get them back or skip waiting ?
You transferred your btc to an address that contains a private keys, so just download electrum as suggested by cr1776 then import your private keys there and you will have all your bitcoin there Exactly. You can export the private keys from Bitcoin Core before it finishes syncing (e.g. dumpprivkey - http://bitcoin.stackexchange.com/questions/5614/using-dumpprivkey-to-make-a-paper-backup ). Then shutdown core (no need to sync it if you aren't using it). Backup the wallet.dat somewhere safe. Import the private keys into Electrum, and go from there. I would suggest that you move your coins from your initial address to an Electrum address so that you can take advantage of the HD addresses there. |

I transferred some BTC into my Wallet
Now i know that before i can use my BTC i need 2 download thoose "4 years of BTC-history"
Can i anyhow skip this download or transfere my BTC anyhow without downloading ?
sorry 4 bad english ~
You can use a lite wallet - e.g. https://electrum.org/#home or one of the other similar wallets. By the way, there are native language sections. |

Pretty much if it is centralized, you might as well just have a database and name it "block_chain" and avoid all the hassles. Then you can say "I am using block chain technology" and roll it out instantly. They miss the point that the shared, distributed ledger is only as good as the fact that anyone, anywhere, anytime can verify its authenticity and that it is backed by the value of the infrastructure and ecosystem behind it.

First let me say this is not a complaint, I just haven't noticed this happen before.
I sent a small transaction with the recommended fees from core (with is my normal practice, I just use whatever fees are suggested):
TxID: 6c37eba28af906b3ed498627b0a05e7e0ae218dc60e8f9bd98981c4aa0b7c74c
I managed to send it right at the start of a biggish gap between blocks, about 40 minutes according to blockchain.info
The following 6 blocks (which took a further 61 minutes) were all effectively full, 998 kB or more; it didn't get into any of those and so it has now been >90 minutes, without a single confirm.
Given I'm not really bothered in this situation (as confirming it is not time critical) it doesn't matter this time; but realistically is there anything I could have done to get it confirmed faster? Would higher fees even help given the blocks are basically full?
You should probably move this to the Technical Support section, but... Do you have bitcoin core running continuously or just start it up, send and shut it down? If the latter, then you may not have gotten a good estimate on the fees. |

I've tried -repairwallet, -upgradewallet, some other random commands. It doesn't seem to change anything. Could I possibly disassemble the wallet (move privkey) or switch the wallet to a different bitcoin program?
You could try pywallet to extract the keys and then import them elsewhere. Beware of anyone asking for copies of these. |

What would it take to run 50+ alt coins as well as Bitcoin daemons on say a VPS or even dedicated server?
Is it possible to create a payment system with this many currencies supported, all from one server? Or would you need multiple?
This is theoretical, but I want to put it into practical use in the future
I think it would depend on the server and the alt-coins and the rest of the software you intend to run. You'd want to beware having hot wallets on the server of course. But with a generic selection of alts, plus bitcoin, one could probably handle it, IF it was a server like one of these: For example, a 224GB RAM, 32 Core, 500GB SSD (or 2TB SSD) server could probably handle it. A server like that would not be cheap (around 1700/month at DigitalOcean). At Amazon EC2 (32vcpus, 244 GB, 640GB SSD range, d2.8xlarge would run about 23616/year). So for someone with the money to invest in it, it is doable. A low-end VPS with 4GB of RAM or even 8GB of RAM wouldn't be a machine I'd try it on. |

It will be mean that Italy will approve bitcoin for their government and I think it is much better as with that bitcoin will also get a full support from the governments and the price will increase more higher.
absolutely right, we will see that bitcoin is trusted by government field. the government would guarantee bitcoin and then bitcoin will be developed in the community italy. How will the government "guarantee bitcoin"? |

Glad to see you recovered your funds. This is a good opportunity to remind everyone of the importance of frequent backups, I save a new copy of my wallet.dat for every ~100
...
Or upgrade to 0.13.0 and then migrate to a HD wallet - but keep a backup of your old wallet.dat(s) just in case. |

Hello,
I have lost access to my classic multi-bit wallet. Hard drive is totally dead and i don't have access to any back up files. I know my passcode key and i see the bitcoin on blockchain.info. Is there any way I can regain access?
Thank you!
As achow101 stated, there is a difference between HD and Classic, he gave you good advice. There are a fair number of people around who are giving bad advice just to get their post count up and get their ads in front of people. Depending on the number of bitcoins stored in the wallet, you could use one of the hard disk recovery services (e.g. ones such as DriveSavers). This would be good for a larger number of bitcoins though. Some of them charge by the GB recovered, and I think they'd try to recover the entire drive. You might pay anywhere from $300 to $3000 to recover the drive. So if you only had 1 bitcoin, it might not be worth it (unless you had other important items there). If you had 10 or 20 or more, it could easily be worth it. |

Tuur Demeester Defends Theymos’ Censorship of The Bitcoin CommunityThroughout the years, there have been a few people in the Bitcoin world who generate a lot of negative friction. Even though their intentions may be good, the way they go about things leaves much to be desired. Censorship in the Bitcoin world is unacceptable, and many people see Theymos as one of the culprits. But Tuur Demeester is supporting his “style”, which creates even more discussion among enthusiasts... http://www.newsbtc.com/2016/09/11/tuur-demeester-defends-theymos-censorship-bitcoin-community/ This isn't a news article, but an opinion piece. The good news is that if someone doesn't like the way things are run, there are hundreds of other places people can go to discuss bitcoin and alt-coins. That is the nature of freedom - people can control their own property just as everyone else can control their's. |

Some Economists Really Hate Bitcoin: An Overview
The vast majority of economists seem to have a serious distaste for Bitcoin. Whenever an economist who has received a Nobel Prize, teaches at an Ivy League school or works at a central bank comments on Bitcoin, they always seem to have something negative to say about the technology.... https://bitcoinmagazine.com/articles/some-economists-really-hate-bitcoin-1473451135 Of course economists on the payroll of progressive socialist authoritarians who want to control the masses of people by controlling the money supply don't like Bitcoin. 😀 Just like ants don't like pesticides. |

Speaking of which, what happens when (if?) computers become so powerful that they can brute force into random wallets with balance? The scenario doesn't seem too plausible in the future.  There have been a ton of discussions about this here and all over the internet. No need to hijack this thread. e.g. https://bitcointalk.org/index.php?topic=1305887.msg13377953#msg13377953 |

Does that mean that no block has been mined in 45 minutes? Why would that be  In average new block should appear every 10 minutes. Bitcoin network recalculates difficulty every two weeks, so such fluctuations can happen. In some new cryptocurrencies difficulty recalculated more frequently, so such fluctuations is rare. It does NOT mean that. Hashing power is quite stable over this time frame and does not cause this type of variation between block times over this time period. You can read more about the distribution of block times in this thread among many other discussions all over the web: https://bitcointalk.org/index.php?topic=192695.msg2009649#msg2009649 |

In short, bitcoin core isn't a deterministic wallet. It generates a random private key/address pair each time you send change to yourself (in reality, iirc, it calculates about 100 pk/addresses in advance).
wallet.dat holds these private keys for you. You can export one of them, but if you don't export all of them, you might lose coins.
Best thing is to do a regular backup of your wallet.dat, that way you're sure all your private keys are backupped.
...
Pre 0.13.0 this is true. As of 0.13.0, it has HD functionality, just to be clear. He didn't say what versions be was using, but if he created the wallet.dat with 0.13.0, then it could be HD - seems unlikely though. |
