 As you can see, I have what appears to be BTC being ADDED to my wallet. When I click on the transaction and look at the transaction details, it shows TONS of addresses on the left and than (I think) the scammers wallet on the right. https://live.blockcypher.com/btc/tx/e6fc6917c4809f5ccfd1e345d1e7e09f716b0bb0f50d371c6f5494e931c6a968So, looking at this, how can I tell exactly what happened? My gut tells me my wallet was used a mixer or to launder the stolen BTC THROUGH (many other people were victims of this). Firstly (because blockcypher looks horrible for large transactions): https://blockchain.info/tx/e6fc6917c4809f5ccfd1e345d1e7e09f716b0bb0f50d371c6f5494e931c6a968So, are you saying that "1DVhaBdbp5mx5Y8zR1qR9NBiQtrgL9ZNQs" address is actually contained in your wallet? if you look through all your addresses, do you see this address? If so, it would indeed appear that the thief has attempted to move the stolen funds through your wallet (1 minute gap between all the funds going in and going out) to try and cover their tracks maybe? If you can't see your addresses in Jaxx easily, given that your wallet is already compromised, just use https://iancoleman.io/bip39/ Put your seed in, I think Jaxx uses a derivation path of m/44'/0'/0', so if you just click the BIP44 tab, you should see all your addresses/keys. Have a hunt through those looking for the "1DVhaB..." address. |

I'm not sure why people are even mentioning "replay"... both Bitcoin Cash and Bitcoin Gold have FULL 2-way replay protection, so: - BTC transactions are NOT valid on BCH or BTG networks - BCH transactions are NOT valid on BTC or BTG networks - BTG transactions are NOT valid on BTC or BCH networks You do NOT have to worry about transactions being "replayed" between BTC, BCH or BTG. Send your BTC where you want... your BCH and BTG are going to stay exactly where they are now  |

if you don't mind sending ALL you transactions as RBF... simply add "walletrbf=1" to your bitcoin.conf Failing that, don't you just add "true" as the fourth parameter to "createrawtransaction"? createrawtransaction [{"txid":"id","vout":n},...] {"address":amount,"data":"hex",...} ( locktime ) ( replaceable )
...
4. replaceable (boolean, optional, default=false) Marks this transaction as BIP125 replaceable.
Allows this transaction to be replaced by a transaction with higher fees. If provided, it is an error if explicit sequence numbers are incompatible.
so something like: bitcoin-cli createrawtransaction "[{\"txid\":\"HEX_TRANSACTION_ID\",\"vout\":0}]" "{\"address\":0.01}" "" true

At that point it becomes interesting in crypto: who owns the accidental deposits?
As with all things in CryptoCurrency... the person in control of the private keys controls the coins... By assigning the value of your coins to the private keys controlled by the shopowner, you cease to be in control of those coins, so "ownership" isn't in dispute. The real discussion is more about morals and ethics, ie. "Is the shopowner morally/ethically obligated to return the money?" Furthermore, what about if we're talking about a large exchange and the process to "reclaim" the misplaced coins by extracting private keys could potentially expose private keys/wallets that could lead to the loss of millions of coins which are "other peoples money"? Also, should the shop keeper be compensated for their time/effort for someone else's mistake? CryptoCurrency involves a LOT of responsibility... people often neglect that part of the "Be your own bank" catchphrase...  |

May I take advantage by asking if anyone can supply a web site address that tells me how I benefit from Bitcoin cash?
For example, if I want to sell one bitcoin, how do I get the bitcoin cash value as well?
You don't get the BCH value when you sell BTC... you get the BCH by having had BTC on a private key when the fork happened... it doesn't matter what you do withe BTC "after" the fork has happened... the BCH will stay with the private key... you get your BCH by importing your BTC private key (or BTC wallet file) into a BCH wallet (like BitcoinABC or ElectronCash). BTW, can someone find my IP address from comments on the internet regarding Bitcoins and trace back to my computer? I'm asking questions on a couple of forums/ comments pages and I hope it doesn't give a crook some ideas.
Probably... it is the internet after all... VPN's and/or TOR are a good idea if you're super paranoid about these sorts of things. Further. I have been looking at ways to make a paper wallet by printing my private and public keys.
The instructions I have found say I have to transfer my Bitcoins to the paper wallet. How do I do that? If I transfer them to my paper wallet, does that make my wallet.dat file useless? I want to keep my wallet.dat file intact so it still shows my bitcoins when I fire-up Bitcoin-qt, but also have the paper wallet as a further back-up.
If you want it to be the same... you'll need to export the private key+public address that has your BTC and print it on paper... the issue will be that if you make any transactions using Bitcoin-QT, it will possibly render your paper wallet obsolete if the change from the transaction is put onto a different (ie. "change") address... Your paper wallet will then have a zero balance... and you'd need to export the private key for the change address and reprint your paper wallet. |

Can i ask why is better create first the two TrezorPassphraseWallet instead to add the Passphrase after?
Because it'll help protect your privacy and also save you some transaction fees... if you go: - Electrum1 -> Trezor - Electrum2 -> Trezor - Trezor -> TrezorPassphrase1 - Trezor -> TrezorPassphrase2 You have effectively linked ALL your BTC together... plus 2 extra transaction fees... Much better to do: - Electrum1 -> TrezorPassphrase1 - Electrum2 -> TrezorPassphrase2 Your BTC remain "unlinked"... and you only do two transactions instead of 4. If you don't care about privacy you can send them all to same Trezor wallet first if you want and then split into two wallets... And if you don't want to keep your BTC separated, there is no need to create multiple Trezor wallets or Accounts. it's clear!
And if i want to just connect my trezor to electrum with "import hardware wallet" procedure? i will have only one electrum wallet?
You will create the "watching only" wallet for whatever passphrase you used to unlock the wallet when you create the Electrum wallet. So, if you connect to Electrum and "import hardware wallet"... and use Passphrase2, you will get TrezorPassphrase2 wallet imported to Electrum... if you use passphrase1, you will get TrezorPassphrase1 wallet imported to Electrum etc. To switch from one wallet to another in Electrum, you need to disconnect/reconnect the Trezor and unlock with the passphrase for the wallet you want to view. |

However, I guess the thing is, how can trust any of these tools? Even with the Windows python tool, there could be malware keyboard loggers on my computer, and I could be giving my seed to hackers...
The code actually asks for your seed to be input in a random order... the device asks for "Xth word" 24 times... much like the advanced recovery mode within the Trezor Wallet WebUI. This makes it difficult to determine the correct order for the words. But yes, if you're concerned about keyloggers... an offline PC, or a live USB/CD distro is the best idea. Are hardware wallets fully compatible with each other? If I get a nano s, can I restore from my Trezor with the seed?
In a word... yes. I've tested the same seed on my Trezor and my Nano S. I believe Trezor use BIP44 while Ledger nano S use BIP39 so you probably can't recover it so better get another Trezor.
They actually BOTH implement BIP39 AND 44... BIP39 = https://github.com/bitcoin/bips/blob/master/bip-0039.mediawikiThis BIP describes the implementation of a mnemonic code or mnemonic sentence -- a group of easy to remember words -- for the generation of deterministic wallets. ie. the use of "seed words" BIP44 = https://github.com/bitcoin/bips/blob/master/bip-0044.mediawikiThis BIP defines a logical hierarchy for deterministic wallets based on an algorithm described in BIP-0032 (BIP32 from now on) and purpose scheme described in BIP-0043 (BIP43 from now on). ie. the use of a specific Derivation Path defined as: m / purpose' / coin_type' / account' / change / address_index By default, all the hardware wallets (for BTC) use m/44'/0'/0' |

You have a couple of options: 1. You can put your seed into the BIP39 Mnemonic tool ( https://iancoleman.io/bip39) click the BIP44 tab... and make sure it is generating the same BTC addresses as the Trezor wallet. For added security, you should really do this on an offline machine (at at least using a live CD/USB like Tails etc), with a downloaded, offline copy of the tool... 2. Move your DASH (just in case), then wipe the Trezor and reload with your Seed to see if it regenerates the same wallets with history etc. 3. Get a 2nd hardware wallet like another Trezor or a Nano S etc... restore your seed onto that device. 4. Restore your seed into Electrum (again, on an offline machine), see if it creates the same BTC addresses as it currently does. 5. Use the python-trezor library and their "trezorctl" command line tool to do a dry-run Personally, I tested with only one device by simply wiping the device and restoring before I sent any coins to it. This actually does work with Windows... I just tried it on Windows 10 with Python2.7 and a Trezor with firmware 1.5.2. C:\Python27\Scripts\pip.exe install trezor
C:\Python27\Scripts\pip.exe install click
Download python-trezor from: https://github.com/trezor/python-trezorExtract it... and then from the directory where you extracted it: C:\Python27\Python.exe trezorctl recovery_device --dry-run

Unless you can find a VPS provider that allows for 200 gigs of storage + 50gigs bandwidth/month for free... then, I'd guess the answer would be no.
Currently the Core blocks directory takes up about 150-160gigs... and a full node (incoming and outgoing transactions) will use up a fair bit of bandwidth/month.

It *is* doable... it just isn't a straightforward "point and click" exercise... you need to find all the UTXOs contained in each 2FA address and manually create and sign a transaction to move these UTXOs to the BTG wallet address of your choice (personal wallet or exchange etc). This means typing in a bunch of commands on the Electrum and BitcoinGold Core wallet consoles.
It also means that you need to have the BitcoinGold "Core" wallet downloaded, installed and fully synced.

I have to disagree. If the purpose of a hardware wallet is that the PK never leaves the hardware, and therefore also should not be loaded on to it. Then there is no option for backing up your PK which means you must be very careful where you put the hardware wallet, that you don't lose it, that is is not stolen, that it doesn't break, etc.
Which I would say is way more likely to happen than my own PKs should be compromised as long as I have followed protocol and generated them myself from a pc that was never connected anywhere else.
More correctly... the PK's (or in the case of hardware wallets, the "seed") should never be on an "online" device. Of course you should backup your hardware wallet "seed mnemonic"... but this should be "offline"... ie. on paper... or, in your case, the "air-gapped" laptop. The problem with your proposal of generating your own PK's, as highlighted by achow101, is that you can't import individual private keys into a hardware wallet. So, you would need to generate a seed, and convert that to a 24 word BIP39 compatible "seed mnemonic"... you could then import that seed mnemonic onto your hardware wallet. Obviously, this would all need to be done on non-networked offline hardware. The methodology for going from a seed to a seed mnemonic is outlined in BIP39 ( https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki#generating-the-mnemonic)... basically generate 256 bit random number + "8 bit checksum" = 264 bits... split your 264 bits into 24 groups of 11 bits... each 11 bits = number between 0 to 2047 = index into word list of 2048 words ( https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt) In either case, paper backups of your seed and/or mnemonic are still a good idea in case of hardware failure killing your offline laptop. |

I would hope that Bitpay should forward that amount to you without charging you for a "network fee"... in my experience as a user (ie. buying things from merchants who use Bitpay as their payment processor), they actually add an extra network transaction fee to your purchase amount to cover the cost of Bitpay consolidating all the payments and transferring to the merchant. For example, Buying an Amazon Gift Card from eGifter.com: $100 AGC = 0.009150 BTC Bitpay invoice = 0.009150 BTC (card) + 0.00026000 BTC (network fee) = 0.00941000 BTC total. You then need to put ANOTHER network fee to send that total amount to Bitpay from your wallet... You can't control the transaction fee that Bitpay charge, but (depending on your wallet) you can control the transaction fee for sending the transaction TO Bitpay As I understand it, Bitpay then use the extra fee paid by the purchaser to cover the cost of transferring the coins to the merchant. According to their pricing ( https://bitpay.com/pricing) they may also take a slice of the 0.00915 purchase price (up to 1% as a service fee depending on your plan/transaction volume)... |

I'm not sure that i have understood correctly what the links say.
Let's make an example.
- I have an electrum wallet with 1 btc and its own seed and Passphrase , and an other electrum wallet whit 2 btc with its own seed and Passphrase .
- I buy a trezor. I create a new btc seed for my trezor.
So far... so good. - I send my 3 btc to trezor, so, all of these btc have now only a seed and no Passphrase.
No... I do not recommend that you do this... - Then i enable Passphrase encryption on my trezor.
- Then i can create two different Passphrase and send 1 btc to my first Passphrase wallet and 2 btc to my second Passphrase wallet.
- So, after that, i have to wallet with two different amount on them.
You should just do this... create the passphrases FIRST... then transfer 1 btc from "ElectrumWallet1" to "TrezorPassphraseWallet1"... and 2 btc from "ElectrumWallet2" to "TrezorPassphraseWallet2"... or, as I stated earlier, you can simply create multiple accounts in Trezor. Refer: https://blog.trezor.io/wallet-accounts-and-addresses-bdfa6b66b037 - The section on "Accounts". You can have up to 10 BTC "accounts" in your wallet... it's a bit like having a checking account and a savings account. The accounts are "separate"... ie. you cannot create a transaction that includes coins from Account#0 with coins from Account#1 in the same transaction... but all the accounts are generated from the same seed/passphrase. If i want to import my trezor's seed on a new electrum wallet, what happen? I will see a wallet with 3 btc, or what else? I don't understand this part  To import the seed into a new Electrum wallet, you would enter the seed, click "options", select "BIP39 seed" and "Extend this seed with custom words"... you'd put your seed in, then on the next screen, you're prompted for the "extra words"... this is your "passphrase". So you would need to create 2 new Electrum wallets... one for each "passphrase"... If you use the "account" method, you'd still need to create 2 new Electrum wallets when restoring to Electrum, but instead of having passphrases, you'd simply change the Derivation Path (m/44'/0'/1'... m/44'/0'/2' etc). An other question: is it more safe use a Passphrase on trezor?
I'm not sure what you mean here? Using a passphrase means you can effectively "hide" your actual wallet... someone could have your 24 word seed, but without your passphrase they will never find your actual wallet... bruteforcing a "strong" password (10+ alphanumerics+symbols) is impractical for current computers (length of time required measured in years etc)... so if your piece of paper with your seed words gets stolen, and you've used a passphrase, you have plenty of time to move your coins before the thief can access them. Without a passphrase, as soon as they have your seed, they effectively own your coins |

You shouldn't need the passphrase to just open and view the wallet. The passphrase is only required for actions that deal with private keys (signing messages/transactions or exporting etc).
Have you tried rescanning? Shut Bitcoin coin down... Then make sure your "old" wallet.dat is the one in the Bitcoin data directory... Then start Bitcoin Core with the -rescan option.
This will force it to rescan the blockchain looking for transactions that involve the addresses in your wallet.

Sorry to hear that... to "close the thread", you'll need to click the "lock topic" option at the bottom of the page, just above the "quick reply" box... or you can edit the first post, click "additional options", select "lock this topic" and then "save".

Your problem, is that you are attempting to use "Bitcoin Core" process... on "Electrum". Bitcoin Core just create a PGP signed "text message" that includes the SHA256 checksums of their download files. Electrum on the other hand, digitally signs the installer files themselves... and gives you a copy of the "signature" file with which you can verify the installer file. Your "gpg4usb" app only seems to support verifying text messages... not verifying the digital signature embedded in a binary installer file. Also, was it really necessary to spam 5 different threads whining that your preferred way of verifying files is not how ThomasV has chosen to implement file verification?  |
