Two questions:
1. What version of Electrum are you using?
2. When you click on the "green dot", it will bring up the "network" window... what is the number of blocks listed next to "blockchain"?

Where is transactions which was sended on nonexistent adress? Where are stored btc, if we send it on nonexistent adress?
There is no such thing as a "non-existent" address... Bitcoin addresses are classified as either "valid" or "invalid". "Valid" means the checksum passes and that the Base58check encoding is OK. eg: 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2 "Invalid" means that the checksum fails and that the Base58check encoding is incorrect. eg: 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN XYou can check validity here: http://lenschulwitz.com/base58The network does not care, nor can it "know", if any given "valid" Bitcoin address actually belongs to anyone or is in "use"... Think about the situation where someone has create an offline paper wallet using dice... how would the Bitcoin network know about the address for this wallet? It can't... so it doesn't care... if the address is valid, any bitcoins sent to the address will be assigned to it... regardless of whether or not anyone actually has the private key for it. |

Well i figure i need a place to hold my bitcoin in case something happens to my electrum. What is rbf?
"Replace-By-Fee"... it is a system that lets you increase the fee on a transaction after it has been sent... useful if you send with a fee that is too low and your transaction doesn't confirm for a while. Okay so when i create a new wallet with new seed with electrum, aren't i still going to have to pay a transaction fee though to get my btc to that new one like with blockchain? Yes... but Old Electrum -> New Electrum = Transaction fee... whereas Old Electrum -> B.info -> New Electrum = TWO transaction fee's  Yes i heard you can have multiple wallets on electrum but i never tried this. So if anything happens with the old wallet, then there is no issue because the btc would be moved to the new electrum wallet right?
Yes... the whole point is to move the BTC onto new private keys that are completely separate from the current ones... so if the current ones are compromised (seed or wallet+password is leaked by putting seed/private keys into fake wallet software or whatever etc), then your BTC is nice and safe because it is already sitting on a new wallet with different private keys/seed  |

what was the conclusion as I done the same!
Sent from Binance account to my Kucoin.
No, you haven't... you've sent BTC from an online service... to a BCH wallet on another online service, for which you don't have access to the private keys... this is a LOT different to sending BTC to a BCH wallet that you hold the private keys for.  I was sending BTC to Kucoin but accidentally given my BCH address instead!! Ive emailed both Binance and Kucoin to explain what has happened... But im assuming its lost in the limbo?
No, assuming your transaction is showing as confirmed, then your BTC will be residing on a BTC address at Kucoin that is identical to the BCH address you sent it to. The ONLY people who can help you now are Kucoin. Given they are an exchange, and most likely using MultiSig "3"-type addresses, your chances of recovery are relatively slim. It is not impossible for them to recover the coins, but it isn't super easy either. Do not be surprised if they say "sorry, can't help" or want to charge you a fee for recovery. |

Yes i meant sending coins to blockchain temporarily. Then download electron cash. Put the 12 word phrase on electron cash... claim bitcoin cash. But after this step, should i immediately sell it on bittrex for bitcoin or usd or another coin? Then once i do that, i have btc or usd or another coin on bittrex. Then i create a new electrum address where it has a new 12 word phrase. Then i send the btc from blockchain to that address. Then i send the btc from bittrex to the new electrum address. If i do it this way, is it 100 percent safe since i no longer would be using the old electrum with the 12 word phrase?
Why would you send it to a b.info wallet first? You're just going to end up with an extra transaction, which means ANOTHER fee + probability that b.info screws up your transaction with a stupid low fee and it gets stuck Additionally, I don't think b.info allows for RBF? But that may have changed since I last used it. If you're going to end up using Electrum anyway, why not just create the "new" wallet with new seed... then send your BTC straight there?  You realise you can have multiple wallets with Electrum at the same time right? You can even have them open at the same time  As for selling or hodling your BCH... well, that's up to you... if you think BCH is going to drop, probably better to sell... it you think it is going to rise, maybe hodl... if you think it's going to hold steady at current values, then you don't have to do anything What it is actually going to do? well... no-one really knows... it's basically just a guessing game |

3. I see now that they have Bitcoin Gold app, can i claim them same way as Bitcoin Cash?
Pretty much... The only difference is that BTG was forked around Oct 24th (depending on your timezone)... specifically it occurred at 2017-10-24 01:20:39 UTC... block #491407... so, you need to use the private keys that held BTC as of block #491406. If you made any BTC transactions (send OR receive) AFTER Aug 1st and BEFORE block #491407, then your total amount of BTG will likely be different to the total amount of BCH... and quite possibly on different keys. In any case, if you move ALL you BTC now to your Ledger, you can simply import ALL you keys from the Bitcoin Core wallet.dat into both a BCH and a BTG wallet and you will be able to get your BCH and BTG. 2. If i remove my Bitcoin app on Ledger, and then reinstall it, everything is there right(with same adresses and private key)? And the same goes for every app/coin that Ledger supports?
Just to clarify, as I think omnz423 didn't quite understand this correctly (As you were not asking about removing the app from the computer, you were asking about removing the app from the Ledger itself)... Yes, you can remove the Bitcoin "app" from your Ledger (or any of the other apps like BitcoinCash, Doge, LTC, Bitcoin Gold etc) and then reinstall it later and you won't lose anything. All the apps generate their wallets from the one seed (backed up by your 24 word seed mnemonic)... that seed is NEVER removed unless the device is wiped/reset (wrong PIN 3 times or manual reset etc). |

got a reply from coinbase they have just copy pasted the FAQ of bch..it was also the fault of Kraken which gave me the option of converting and sending bch to btc address.
the system game the option and quantity of btc which is processed and confirmed as success when i transfered.
Kraken says contact coinbase..and coinbase is not interested
Ahhhh ok... so what you're saying is that you withdrew BCH from Kraken... and sent it to a BTC address on Coinbase? If so, they only people who can help you are Coinbase. They will need to retrieve the BCH for you as they are the only ones with the private keys for the address you sent it the BCH to. Also, it isn't Kraken's fault that BCH and BTC addresses are identical... There is absolutely no way for Kraken (or any other wallet/exchange provider) to be able to prevent this. If you want to blame anyone, blame the BCH devs for not implementing unique addresses... and yourself for not being more careful. |

Can i move wallet to any wallet, which allow «double spend» and try «double spend» there? Is Electrum support «double spend»?
Not really... most "good" wallets are purposely designed to prevent double spends. For most wallets, you need to try and remove the transaction from the wallet and then try recreating it with a higher fee. Not all wallets allow you to remove the transaction. Correct. Aaand i migrate from MBC to Electrum. Now i confused again — in Electrum i see positive balance (1.97BTC), two confirmed transactions and don't see both unconfirmed transactions. Is it mean that now i can «double spend» BTC?
That just means that the Electrum server you are connected to, does not have those two transactions in it's mempool. It seems the transactions are slowly dropping out... it is still visible on b.info, blockexplorer.com and btc.com, but has dropped from blockcypher.com and blocktrail.com. This is a good sign. Hopefully, it will either drop completely or it will eventually confirm... You could try to spend from Electrum now, but I would advise against it... it will just complicate things and make it a bit messy. In all likelihood, the network will most likely reject your transaction as a double spend anyway. |

... where i can import my private key and seeds to access my assets ?
Into any compatible wallet... so you go get a BTC wallet, a BCH wallet, a BTG wallet, an ETH wallet, a DOGE wallet, a LTC wallet, a XXX wallet... you get the idea... If you're lucky, there will be another multi currency wallet (like Coinomi) that will take your private keys/seed and give you access to your "assets". I honestly don't know if Coinomi works with Exodus seeds... there is a good chance it will, but I've not tested it. If you're THAT concerned about it, then I would suggest that you start testing a few different recovery options NOW, before you go too far down this road. |

Thanks for your reply! It seems, that this is all far to complicated for me as a "standard" user.. would appreciate an "easy" solution to get my Bitcoin Cash back..
Seems like I didn't quite make myself clear. Basically... there ISN'T a solution... easy or medium or hard... BCH sent to a BTC SegWit address is NOT able to be recovered. |

Then it would appear that you imported a public key (or address) and generated a "watching-only" address in your wallet that had no private key behind it... and you then received coins on that address. And obviously, without the private key, those coins are effectively locked in that address forever. As the saying goes "No private key = no coins"  |

Do you still have a copy of the wallet.dat before you ran -salvagewallet? Apparently, salvagewallet can make things worse... so I'd suggest that you start each attempt with a fresh "copy" of the wallet.dat file... and only ever work on the copies In any case, your recovery attempt with pywallet seems a little off... as far as I'm aware, you can't run it on a file... only on disk/partition. So, my suggestion is to put the wallet.dat on a "small" USB stick... ideally less that 4GB... then use: python pywallet.py --recover --recov_device=/dev/sdb1 --recov_size=4Gio --recov_outputdir=./recovered
as per this post: https://bitcointalk.org/index.php?topic=1404609.msg14257235#msg14257235Obviously replace /dev/sdb1 with whatever the actual path to where the USB stick is mounted... I've done this on a Windows box and it was able to recover keys from an encrypted wallet.dat... if you can create a 1GB partition on the disk, even better, it'll reduce the time it spends scanning by quite a bit! |

Am i correct, that your suggestion is to send «unconfirmed» BTC from HD back to MB Classic? It must be one big transaction or two smaller (as i send it to HD)? Where can i read more how this method works?
Sending unconfirmed BTC from HD Back to MB Classic won't do anything but put another unconfirmed transaction in the mempool... he got it backwards. I think he meant to say "send again from MBC to MBHD"... effectively, a double spend. The only problem with this is that you can't easily do that with MBC. It will not let you double spend. So you'll have to do it manually. Did not know about that fee so important, shame on me. But what if my transaction will never be picked up, because of low fee? Is there any «timeout» for confirmation, when transaction canceled and BTC going back to wallet?
Theoretically, it could stay forever... realistically, a few days assuming no one rebroadcasts your transaction. If you want it to drop... DO NOT open your wallet or MBC until you have seen that the transaction is no longer showing on block explorers like blockchain.info and blockcypher.com etc... If you open your wallet, you run the risk that it will rebroadcast the transaction again! @HCP, what do you think about «Fix Unconfirmed transactions» option from @davecarter?
Double spending is not easy to pull off... you will need to manually create the transaction and then find some nodes to broadcast your new transaction. Most will refuse it since your first transaction is already in the mempool... also, there is simply no guarantee that the second transaction will be confirmed ahead of the 2nd one... Could i migrate wallet from Classic to Electrum now, or i need to wait before BTC (somehow) come back?
You can do it now... if you import your keys to Electrum, it should automatically find all the current transactions anyway... It won't necessarily "fix" the current situation, but it won't make it any worse |

Yes but it is not about promo offers. Its more about the customers don't know how to pay by bitcoin. So there must be a way to provide them a solution which supports easy bitcoin transaction by known payment methods: Like they can buy bitcoin via paypal and pay us via bitcoin easily...
I think your thinking is a little flawed here. Why would a customer go "Paypal -> Bitcoin -> You"... when they can go "Paypal -> You"? Likewise for CC... why "CC -> Bitcoin -> You"? Where is the "value add" for the customer to get involved in Bitcoin? If you're not offering any incentive for using Bitcoin, what is the point? Only people who already have Bitcoins will use Bitcoins to pay you... otherwise, they'll just pay with Paypal or CC. |

So I figure my bitcoin gold should be on the "My Wallet" and the associated memoric seed - i used the Mnemonic Code Converter but it doesn't work. Coinomi says no funds. I can see my public address 13DHVtddXSzfieFL9M66ucWgdDxgByy1U3 is derived and using the associated private key. But when I check - According to the bitcoin gold website my coins sit with the following public key: 1Nqhof6fqp11pUrnRW8AuYcLnBzZKKVrzd Which is the FROM address on the transaction I made after the snapshot... https://blockchain.info/tx/8604216bd08691fe6b6cb9a7c7b4ea2c189fbcd65b61a687db8c8f18e2efae45I thought 1Nqhof6fqp11pUrnRW8AuYcLnBzZKKVrzd applies to "My Wallet" but it doesnt come up as a derived public key. It will... but not using the Derivation Path you think, because as Potato Chips has already mentioned... 1Nqhof6fqp11pUrnRW8AuYcLnBzZKKVrzd is a "change" address... so you need to search the "Internal" addresses... Using the Mnemonic Code Convertor ( https://iancoleman.io/bip39/) put your seed in, click BIP44... if you don't see your 1Nqhof6fqp11pUrnRW8AuYcLnBzZKKVrzd address generated, change the "External/Internal" value to 1 (BIP32 Derivation Path should display as: m/44'/0'/0'/1)... and then start checking the addresses... you should find it |

With regards to item #1... What happens if you enter the following URL into your webbrowser: https://blockchain.info/wallet/ENTER-YOUR-WALLET-ID-HERE?format=jsonfor example: https://blockchain.info/wallet/9bb4c672-563e-4806-9012-a3e8f86a0eca?format=jsonDoes the system prompt you to authorise the login attempt via Email? Do you get sent an email asking to confirm the login? If so, click authorise and try and load the URL again. You should see the wallet.aes.json text which you can copy/paste to a text file in preparation for using btcrecover. Do you have the email address originally used to register the wallet? If so, you *might* be able to get the Blockchain.info support people to supply you with the wallet.aes.json... which will contain the encrypted "payload" data for your wallet... You'd just need to run the gauntlet of ID verification etc. But I've heard it is possible. |

Sure, SPV wallets like Electrum (basically only Electrum, which is the only one I know with solid devs) may be a good entry point for newbies, but I don't like at all the idea of a seed being able to spawn out of nowhere my entire private key history. Don't you see this as a risk?
You realise that since v0.13 Bitcoin Core has, by default, been a seed based HD wallet right? It may not give you a "12 word seed mnemonic" to write down, but nonetheless, all the addresses are generated from a seed. It's just as likely that someone will randomly spawn your Bitcoin Core wallet as they will an Electrum wallet... Which, in both cases, is so miniscule that the chance of this happening, is for all intents and purposes, ZERO. There was a thread post somewhere where someone did the math... You're more likely to get hit by lightning while taking a crap, once a year, every year.. For 17 years in a row! So, how about b2x? Which wallet is the best to claim free b2x? I'm not so sure right now.
That's completely irrelevant... B2x got "cancelled", so there is nothing to claim...  |

How do you increase your sales by bitcoin billing?
Have you considered offering some sort of promotional rate for folks who want to pay by Bitcoin? Maybe a small discount or a free month or something like that... It would help promote the fact you have a new payment option and with Bitcoins current trend, probably would not cost too much in lost revenue as the gains in BTC value would hopefully offset it. People love "free stuff"™ and discounts etc... You can guarantee that if users can save a buck or three by using Bitcoin, they'll do it! If you have a customer base who have opted in for mailing... Highlight the new payment option in an email campaign. Social media? I mean, this stuff is basically marketing 101... Just putting a "pay with Bitcoin" button isn't going to do much... You need to basically have the equivalent of giant flashing neon signs highlighting it... "People"™ are lazy and "blind" |

I understand it's better to transfer all of my BTC out before using electron cash but the network's fee now is so high, transfer 1.5 BTC costing me 0.16 (more than 10% ) It hadn't propagated well... seriously... you wonder why your fee was so big? Your transaction was 18,217 bytes!!?!  normal transactions are like 226 bytes... No wonder it wanted a fee of 0.16! Anyway, your transaction has now been pushed via a bunch of transaction broadcast services... so the ViaBTC accelerator should be able to find it... wait until the start of the hour and try and accelerate it. |
