Bitcoin ABC is a BCC only wallet... It does not work with the BTC network or BTC transactions.
You will need to take the private key for the address that you sent the BTC to (Help -> debug window -> console, and then use the "dumpprivkey" command) and then import that private key into whatever Bitcoin wallet you want to use (or sweep the coins from it into a Bitcoin wallet)

MultiBit is dead - https://multibit.orgIt was a popular lightweight wallet that came in two flavours ("Classic" and "HD"), but after it got sold to KeepKey it went downhill until it was so old and outdated that they couldn't be bothered developing it any more to keep up with changes to Bitcoin and they made the decision to kill it. Do NOT use either of these wallets unless you want your coins to get stuck in low fee transactions or "corrupt" wallets  |

TBH, Such threads create a fear as i am about to start using Electrum from today.
Edit: Please create your own thread. Thank you for the reply. Yes, i did activate the 2FA. Maybe that's the reason why they asked me my email ID. Yes, this is the reason it asks for your email address. The 2FA wallet feature uses TrustedCoin API, and they require your email address when you agree to the Terms and Conditions:  This is normal, and, for Electrum 2FA, I'm fairly sure they don't actually send you any confirmation email... I believe the email address is used purely for creating an "account" with TrustedCoin so that when you buy prepaid 2FA service fees, they can track your account credit. And possibly receive notifications when a transaction is sent... |

It would appear that he is talking about "multicoin" wallets:
Exodus - Multi coin, closed source
Coinomi - Multi coin, semi open source (apparently very outdated repo)
Jaxx - Multi coin, technically not "open source" as such, but apparently you can view the code.
So, I'd suggest checking out the code that is available for Jaxx and/or Coinomi if you want some idea of how "multi coin" wallets are coded

If you're just going to write stuff down on paper... Why bother using Bread wallet and possibly leaving digital traces behind?
Just follow the traditional "tried and true" methods of creating paperwallets "offline"... Get a dice, roll it 100 times etc... Or use an offline computer (Live CD/USB boot Disk with non network OS) to generate your paper wallet...

When you select BIP39, Electrum does NOT do any error checking on the text entered. So, if you got one character incorrect it would not detect it, and you would end up generating a different wallet to your Ledger wallet. Try and restore from your Ledger seed again, but this time TRIPLE check all the words are spelled correctly, no capital letters etc. Also, what derivation path did you use? It should be m/44'/0'/0' for a ledger wallet. Also, The Ian Coleman till is safe, but still recommended to download a copy of the page and run offline (instructions are actually at the bottom of that page  ) |

Guessing you haven't heard about "OpenBazzar" then? https://www.openbazaar.org - "A FREE ONLINE MARKETPLACE. NO FEES. NO RESTRICTIONS. EARN BITCOIN" |

... but i am not sure how you mark the transactions as RBF in Core. i think you have to do it through command line!
but Electrum for example has RBF option in the preference which is as simple as checking a box...
There is the -walletrbf command line argument (defaults to "false" as this is an "Opt-In" feature... But like all the command line options, you can simply add it to your bitcoin.conf: Ref: https://bitcoin.org/en/release/v0.14.0#opt-into-rbf-when-sending |

Did you do anything with the wallet like send and/or receive funds? Wondering if it is a gap limit issue and generating new address(es) is why it suddenly found coins...
Most likely though it's probably related to issues with the network and/or server due to the use of TOR...
Have you tried using without TOR?

4) Install pc version of Jaax wallet. But this did not show my Android wallet balance When you did this, did you set the PC version as a new wallet or did you "restore" using your original backup seed? Does "did not show my Android wallet balance" mean the balance on the PC was initially zero? 5) Follow Jaxx instructions to pair/sync wallets.
6) Balance from Android disappears.
It is this order of events that leads to me believe, as I told you earlier, that you have put an incorrect seed into the android device... "Pairing" should not have altered anything on the Android device unless you did it the wrong way round and changed the seed being used on the Android device, instead of putting the Android seed into the PC wallet. As per this warning within the Jaxx wallet:  You say you can see the transactions from Coinbase to your wallet... And the addresses in those transactions still contain coins. Can you see those addresses in your Jaxx wallet history at all? If you put your seed into https://iancoleman.github.io/bip39/ (recommended to download a copy of the page and use "offline") and select BIP44... You will get some addresses generated at the bottom of the page, are the addresses that you sent coins to from the Coinbase/ABRA transactions shown there? If not, then it is highly likely you have got the "wrong" seed... |

Sounds like you need to read this: https://en.bitcoin.it/wiki/Coin_analogyAnd this: https://en.bitcoin.it/wiki/ChangeYou attempted to send 50 BTC, but your biggest UTXO looks to have been 49.99915808 BTC, so your wallet added in extra inputs to make up a total of over 50... Not sure why it needed to use another 12 inputs when pretty much any of the other ones with would have been plenty for 50+fee! Possibly some weird glitch in the UTXO selection algorithm that your wallet is using??  Anyway, it totalled up 88+ BTC, but you only wanted 50, so it put the remaining 38 into a change address in your wallet... |

For the record... A "kilobyte" in Bitcoin is 1000 bytes, not 1024.
Also, "compressed" addresses, would only be around 148 bytes per input, so using 180 may result in overestimating the size in some cases.

No... the fee is not "decided by the network". The fee is entirely decided by the user and/or the wallet generating the transaction.
You are free to use any fee that you like regardless of the current condition of the network, like how many transactions are in the mempool or what fees other transactions are using...
However, what people need to realise is that if you choose to ignore the state of the network and use a "low" fee compared to the majority of unconfirmed transactions, your transaction may sit in the mempool for an extended period of time as miner's tend to prioritise transactions based on the fee used... This will become even more important as the block reward decreases with each halving.

I can guarantee that there is no script in existence (or that can be generated) that can provide +EV outcome... And the longer you play, the more likely it is that you will lose. House edge cannot be defeated in the long run... It's simple maths really. Your best bet is to invest in the house bankroll  |

You don't really have a private key for "a transaction"... You have a private key for an address that is used in a transaction...
The Android mobile app has a limited subset of the available options that the desktop version has... So you can't see the individual private keys like you can using the desktop version. The most you can see is the seed (and master public key etc)
So you would need to create a copy of the wallet in the desktop version (using your seed), identify the address that is used in the transaction that you are interested in (right click the transaction in the list and select "show details"), then on the "addresses" tab (view -> show addresses) you can right click on the address you want the key for and select "private key".

My question is, by hitting that Lock button on the Accounts tab, did it setup a PIN for him? Or is that option only available when a PIN number has already been created?
The "Lock" option is ONLY available if a PIN Code has already been setup previously... So, he must have setup a PIN and forgotten what it was. So, I'd say it wasn't entirely your fault that he is now locked out. I'd suggest he tries his "common" PINs... 6 numbers required if I'm not mistaken. |

Mocacinno, I have a question concern what Boyptc said and the question is. Is it possible to update paper wallet? If yes,how?
That depends on what you mean by "update"? There isn't really anything else you can "update" on a paper wallet... it is effectively just a private key and public address written on a piece of paper... what are you wanting to "update” exactly? Do you mean "can you send more money to it?" ? if so, the answer is yes of course you can... it's just like any other Bitcoin address. |

What version of Electrum are you using?
Is Electrum connected to the network and synced OK? Do you see a green dot in the bottom right corner of Electrum window? or red dot? or blue arrows?

To be honest, Keepkey is quite expensive and large... and essentially does exactly the same job as the other two... As for Trezor or Ledger Nano S... the differences between the two aren't really that great, they generally have the same features (if implemented slightly differently)... so I would suggest that your decision will generally come down to personal preference (and most likely price ) Price: Trezor €89 vs. Ledger €58 Form Factor: Trezor's Square-ish design with "larger" screen and front mounted buttons vs Ledger Slim USB stick swivel design with side mounted buttons AltCoin Support: both support most common coins Colour: Trezor comes in three, Ledger in pretty much one Availability: can be a bit hit and miss for both... Trezor seems to be slightly easier to buy immediately Ben over at "BTC Sessions" on Youtube has a fairly decent 3-way review of these hardware wallets: https://www.youtube.com/watch?v=j_LcJ3ccV4sFor the record, I own both a Trezor and a Nano S... |
