Are you sure you are using the correct passphrase?  My BTC wallet was bitcoin core ver. 0.12.1 After sending my BTC to another address, and waiting for two days status was 0 confirmation, maybe be because the transaction fee was not enough, So I found a solution from google, -salvagewallet, then it seemed to work But today I try to send my BTC again, after I insert my pass-phrase, a window show up which says assertion failed program:C:\........bitcore-qt.exe file:wallet/crypter.cpp,line 190 expression: false if click ignore button, it says pass-phrase incorrect. if click retry, it says runtime error. don't know how to solve this problem  |

I too would suggest this could be a memory issue. How much ram do you have? 32 bit systems with little memory can be problematic.

Do you have pkgconfig installed? Which version of Bitcoin core?

Payment API.
The site is the web investment sector.
If you really want help, please answer the questions. |

maybe you can try a bootstrap. or copy and paste the files in another location and have em ready to copy them back again once corruption happens.
Using a bootstrap is a bad idea and has been since version 0.10.0. |

Does anyone know me know how to do to get the API Key?
Because I have already sent the request for the site, but received a return that was refused without at least clarify the reason.
Has anyone here ever get that key? Because I talked to other developers and they said they also failed.
After all what requirements really needed to get that key?
What site? What api? |

I GOT IT!!!
I had made backed up my wallet multiple times. During one of those times, I figured I might as well just copy the entire bitcoin directory. Turns out the correct wallet.dat was in the copied file, not the backed up wallet.
Thanks everyone for your help! This 3 day struggle has been a big lesson for me.
Good news. Always backup. 😀 |

Are you sure the 12 word phrase you wrote down was entered/written down correctly? There is no central authority to get your bitcoins back, you need the private keys.

Is the old wallet.dat present in a backup? (Assuming it really isn't anywhere on the drive.)

I have downloaded the torrent file recommended in the forum. Using bitcoin core. Can someone walk me through the necessary steps to use the file data in bitcoin core? Thanks
Whomever is recommending this is giving bad advice. The torrent has been slower since 0.10.0. Just let core sync on its own. |

"a Windows wallet"? Which one? Version? Windows version? What version of MinGW is this?

So I recently purchased roughly .025 mBTC off of Indacoin and had them sent to my empty Electrum Wallet. My Electrum wallet is now telling me I have 26 BTC. No, not .26, but 26 whole Bitcoins. I know that's not true because I checked the block chain and it still shows the transaction being .025. But now I have no way to know what my actual account balance is and when I sent out the .025 btc to a different wallet it is entering this other wallet as only .0000229 btc, yet my Electrum wallet seems to be completely empty now? Can anyone please tell me what is going on and how I can fix it? I'm literally just pouring money down the drain at this point. This issue has happened to me once before and I have already tried re downloading the client and getting a new wallet.
This probably belongs in the electrum section, but what units do you have it set to in electrum? Can you provide the transaction IDs? |

Also just be really careful that these are truly random if you intend to store value there. This is often a tricky thing and many people have been caught by using either not truly random prngs etc

What does
getconf ARG_MAX
Show?
There may not be another solution except recompiling since I don't think xargs would help here.

What if the attacker tries to guess all private keys?
...
They would run out of time and energy in the universe first. (*At least with our understanding of physics today.) |

OP, you are completely and absolutely wrong. The private keys ARE NOT randomly generated characters. They are actually 256 bit numbers. This means that the total number of possible private keys is 2^256 - 1, which is a ridiculously large amount of possible private keys. Those private keys are converted into the characters that you see through a process known as Base58 Check Encoding ( https://en.bitcoin.it/wiki/Base58Check_encoding). You cannot just throw random characters together to get a private key because it will probably fail the Check part of Base58 Check Encoding. The Check is the first four bytes of a SHA256 checksum of the private key. Note that most Bitcoins are spendable by addresses, not public keys. Addresses are only 160 bits, and any private key whose public key hashes to the same 160 bit address is able to spend the coins at that address. So for most coins it's "only" a 160 bit search to find a private key that can spend them. You don't need to find the same private key as the proper owner of the coins, you only need to find one which gives the same address. Of course, a 160 bit search is still impractical to carry out. But it's a lot easier than a 256 bit search. and in this case: Bitcoin (cold address)-> person can coincidentally create an exact same account number (cold address) . If someone uses something non-random, sure. E.g. "Dog" as a "brain wallet" or a non random PRNG. Otherwise, no. Saying otherwise is either FUD or not understanding math etc as Foxpup etc has explained. |

I know this isnt strictly bitcoin related but im sure most people use this on various exchanges etc. My problem i have is i cant seem to find a backup option inside google authenticator so that if i ever lose my phone or break it i can recover all my accounts.
Anyone know how this can be done, I know titanium backup is capable of this but obviously ive not rooted yet.
This is definitely off topic for this section, but there is always Authy as an alternative. |

Downloading the bootstrap is bad advice and is often slower than downloading the blockchain with bitcoin core (since v 0.10.0, iirc.) |
