what's an archieving website? So what am i supossed to do?
An archieving website is used to 'make a copy' of sites. Its used to kinda have a proof in case the transaction disappears and the support doesn't want to resolve your issue. It might also be worth to note the raw transactions of your chain of unconfirmed tx's. In case they get dropped (forgotten by the network) you can rebroadcast them using online services[1]. Your raw tx's can be found by adding ?format=hex at the end of blockchain.info transaction links. Example: For the last tx in the unconfirmed tx chain (your transaction) ( https://blockchain.info/tx/77db70f395d1dce8eb95a6bbb9ea9f6435e6d673384c78d034561b9f2ecd93d0) the raw tx can be found here: https://blockchain.info/tx/77db70f395d1dce8eb95a6bbb9ea9f6435e6d673384c78d034561b9f2ecd93d0?format=hex020000000001052c22b12bd84dc71207f88061a3109b5e99b782b4cad30d67069c0e177c0d58e500000000171600140976ae89087e12920490628529bfe4a9107439b1ffffffffadacee024b636b9730959eb4d269c4729642bd024

My advise would be to wait if those tx's will get confirmed and contact their support if it won't arrive in an appropriate amount of time. [1] Online services to broadcast tx's: https://live.blockcypher.com/btc/pushtx/, https://blockexplorer.com/tx/send or https://blockchain.info/pushtx |

ok then how can i transfer it into another address or sell if i want.
As you can see in blockchain if you paste my address and search you can see my purchases.
The only thing i am interested is how can i transfer it in a wallet like blockchain or electrum and sell if i want.
I think you didn't fully understand how bitcoin works. First, i would suggest to read this: https://en.bitcoin.it/wiki/Private_key. Afterwards, the address which you claim to be yours.. how did you generate it? A watch-only wallet is basically a block chain explorer for your one (or multiple) address(es). You can't just spend from this address. You need the private key. The private key has been created the moment you generated your address. So.. until you have one of the following, you won't be able to move/access the coins: 1) a backup mnemonic seed (12/18/24 words) 2) the private key for your address 3) a backup of your wallet-file ( not watch-only-wallet; you need a wallet file which contains the private keys!) |

Your link shows a transaction, not a block. Transactions are going to be included in a block (when the miner of the block chooses to include them). Your transaction has been recieved by several nodes on the bitcoin network (Thats when you see your transaction in blockchain explorer). They did not confirm this transaction yet. Thats why you can see the 'unconfirmed' resp. '0 confirmation' in those explorer. With a fee of 124 sat/B it will take some time until it will get confirmed. Maybe until the backlog of transaction lowered a bit. You can read more about stuck transactions here: https://bitcointalk.org/index.php?topic=1802212.0If your transaction will get dropped and you don't recieve your coins within several days/weeks, you should contact hibtc, since they are the only one able to fix that for you (+ its their fault). |

I told them my wallet has zero balance and they told me they will "re-broadcast it". I am not sure what that means. So frustrating  You should awnser them and reply that the inputs of the transactoin already have been confirmed in a conflicting transaction. Include the ID of the conflicting TX ( https://www.blocktrail.com/BTC/tx/bc885333b54b5f81865943cb811b9d1a022929fb0250160468860546b45fca3a). They definetly made a mistake (or intentionally tried to not deliver your coins). Quite a few people are having issues with wallofcoins. But the majority seems to give positive feedback. Not sure how much you can trust these feedbacks. |

As far as I'm concerned, his refusal to uphold his side of the deal makes him a de facto scammer in this situation regardless of whether that was his intention or not. I was presented with a QR Code and asked to send bitcoins. I scanned the code and I sent the coins as asked. I held up my end of the deal. I expect the same of the counterparty regardless of whether they accidentally or intentionally gave me the incorrect address. As far as I'm concerned, refusal to follow through when I can demonstrate that the bitcoins were sent and confirmed as requested makes one equally a scammer regardless of the fact that he may not have received the bitcoins that he wanted.
I completely agree with you on that statement. But unfortunately most people just have one thing in mind, money. I hope the loss is relatively low compared to your average transactions. This way this sour lemon may still be worth the lesson learned for future transactions :/ I wish i could live in a world where its enough to keep myself secured, instead of having to trust everyones mindset regarding security. |

The address wich I used is from binance.com for depositing BTC. This is why i used it twice. Could that be the problem?
I'm not 100 % sure if binance supports multiple deposits to the same address, but generally they do. However, this is not the reason for your problem. It seems like core didn't broadcast your transaction while still verifying blocks. Is core up to date at the moment? It should show > 502.883 blocks. And just in case , is there anyzhing i can do on my wallet to cancel that transaction ?
You can use the startup parameter --zapwallettxes. This command removes all transactions from your wallet which hasn't been included into a block yet. First: Backup your wallet!Afterwards open the command line (i assume you are using windows) with 'cmd' in windows search. Open core with the following command: C:\Program Files (x86)\Bitcoin\bitcoin-qt.exe --zapwallettxes=1. Thats the standard path. You need to adjust it to your actual path to core. |

Hello guy, let's say someone sent me his private key.
is there any way to secure the bitcoin, don't let him to use the bitcoin on the shared private key?
without making a new transaction to the new wallet?
You simply can't 'secure' a private key which is already compromised. If your private key ever gets known to someone else it is compromised. And once compromised, always compromised. The associated address shouldn't ever be used to store/recieve funds. Not possible. If they send you their private key for an address, they can do whatever they want and you can do whatever you want.
I want to add that in most cases a non-trustworthy enough channel is being used to communicate the private key ( e.g. email). So despite the fact that the previous (and overall, second) owner of your private key could just easily access the funds there is quite a high risk with mails being exposed to nosy people with medium technical knowledge. Whether its the cache of the browser, screen capturing malware, local packet sniffer,... a lot of possibilities. I, personally, wouldn't trust an online communicated private key at all. |

I just configured My Ledger Nano S yesterday and got the same issue.
Thats not an issue at all. Read the previous posts in this thread. ...
In Blockchain.info I saw at the same time 2 transactions + Surprise: Final Balance: 0
...
Conclusion: (not sure if by design or not but) when sending BTC from your Ledger, you will have at the same time 2 transactions: 1 to the destination address, second to another address that is associated to your Ledger, also.
I would suggest you read https://en.bitcoin.it/wiki/Transaction and https://en.bitcoin.it/wiki/Change. When sending BTC you create 1 transaction which usually consists of 1 input and 2 outputs (1 input / 2 output is the case when: input > amount_to_send) Your input will be 'converted' to 2 outputs. 1 output will be the amount you actually send and the second output will be your change. |

Did anyone buy Ledger from their site and pay Bitcoin for it?
It scares me a bit because Bitcoin has no supervision.
Is there anyone who did it and everything was fine with him and he got the Ledger without problems?
As long you are buying directly from the official site ( https://www.ledgerwallet.com/) it works smooth. I bought one myself (with btc). You don't have to worry when paying with bitcoin. Yep. I chose Trezor a couple of years ago, but was recently going to get a Ledger because of the amount of different coins it holds until I heard about the tampering.
Tampering? You don't really have to fear of recieving a tampered device. The nano s runs an integrity check at each start up. Additionally they have a guide published to open the nano s and look if it has been tampered with additional chips, etc.. You can read more about the anti-tampering method on their site he: https://www.ledger.fr/2015/03/27/how-to-protect-hardware-wallets-against-tampering/An on how to check the integrity hardware-wise: https://ledger.zendesk.com/hc/en-us/articles/115005321449-How-to-verify-the-security-integrity-of-my-Nano-S- |

I'm very careful about what is allowed to run on my phone. I've checked it over since this event. My phone is fine.
In case of you both being a victim of a 3rd party malicious software it would be interesting to know whether 1) he was using a malicious version of mycelium or 2) he had any other form of malware on his phone - He continued to contact me after we went our separate ways and came across as genuinely distraught about the entire situation whereas he could more easily have simply disappeared and never contacted me again once he was successful in his "scam"
Is there a chance of retrieving information about the integrity of the version installed on the phone of your 'partner'? |

Hey guys, I know It's an old thread, but my antivirus
finds new infected files every 5 minutes
always in the same directory.. I can't do a system restore because it's windows 8.1 recovery error 0x80070005
And every single infected file ends with .pyc
e.g.: bitcoin.pyc
.pyc are compiled python files (modules loaded in scripts). Did you already try to do a full scan of your pc with your AV? How is this problem related to electrum? Did this problem start occuring after you installed electrum? If so, did you check the signature or at least the checksum? You can find the signature for the current windows installer [1] and the standalone executable [2] on their official site, just like the ThomasV's PGP key [3]. You can verify your files (if you have gpg installed) with gpg --verify electrum-3.0.3.exe.asc electrum-3.0.3.exe in your command line. [1] https://download.electrum.org/3.0.3/electrum-3.0.3-setup.exe.asc[2] https://download.electrum.org/3.0.3/electrum-3.0.3.exe.asc[3] https://pgp.mit.edu/pks/lookup?op=vindex&search=0x2BD5824B7F9470E6 |

Another 15 minutes of investigation and we discovered that the address displayed by Mycelium did NOT match the QR Code displayed by Mycelium.
~snip~
As far as I can tell, they must have some sort of malware on their phone, or some hacked version of Mycelium that is replacing the QR Code with a scam code.
~snip~
~snip~
If I assume for a moment that he wasn't intentionally scamming me, then malware on the phone is the only other thing I can think of.
~snip~
In my opinion you most likely got scammed. But without any further information thats just my first guess! May i ask how you found out that the displayed address doesn't match the displayed QR code? If you used your phone to do that it might also be possible that your phone (instead of theirs) is infected with malware. It may be more likely that your counterparty had an infected version of mycelium / malware, but i wouldn't completely exclude this option. I'd suggest to (at least) run an anti virus check on your mobile and/or check the QR scanning a few times. |

I am now trying to reinstall the bitcoin chrome app but i just cant find it in the uninstall program feature in windows. I see my other wallet apps there but not the bitcoin app.
The bitcoin wallet app by ledger is a chrome app and therefore can only be installed/uninstalled via chrome. You have to open chrome and type chrome://apps into the URL bar. You will be able to open/uninstall the app from there. Are all of your applications (ledger manager, bitcoin chrome app, nano s firmware) all up to date? Ledger manager should be >= 1.0.3Bitcoin chrome app should be >= 1.9.13Nano s firmware should be >= 1.3.1 |

I guess it was too hard to raise blocks to 2MB or 4MB for let's say 1-2 years, while the scaling problem is issued, right? These people gotta be stupid.
The segwit softfork (not segwit2x, or whatsoever) basically increased the blocksize to 4MB already. But to make use of the 'more transactions per block' change, people would have to use segwit addresses, which make transactions notable smaller. If everyone would use segwit, the blocks would be filled with up to ~4x the amount of tx's before segwit was introduced. Thats more than enough short-/mid- term scaling until the LN takes place. But people actually have to use it. Currently about 10% of all transactions are being sent from segwit addresses. |

TX : be8cf44fbf4b03eb64e9ec260dd3d49f2cdda4880d4426b84347baf818a12e6f
sold stuff, someone sent me money. now they cant be seen in blockcypher, but blockchain shows them
is there anything that can be done, or did i got scammed?
You should make sure to rebroadcast your transaction when it slowly gets dropped, to make sure it won't completely disappear. This is the raw transaction: 010000000379a0552e911cde2087040631cb2fd0934e52eb6bdf4cb598ae2a5814134f223d000000006b4830450221008edd969cf5223dfca5f1fd8a41232d648207fd051901ce03ca

(without spaces) I pushed it via blockexplorer.com. Here are a few service which you can use to broadcast your transaction: https://blockexplorer.com/tx/send, https://blockchain.info/en/pushtx, https://live.blockcypher.com/btc/pushtx/If you want to make sure this tx will get confirmed for sure, you should try a child-pays-for-parent. Make a transaction with your unconfirmed input to yourself and set a fee which is high enough to pay the fee for both transactions. Once a miner comes across your second TX he will include it (together with the parent tx) if the fee paid is high enough. You can estimate a fee here: https://estimatefee.com/ |

This vulnerability still can be exploited. It just can't get remote exploited via the internet.
Someone knocking you out (or walking to your pc, plugging an usb stick in and out) and using this vulnerability is (theoretically) still an option.
if someone has physical access to your computer, there are easier ways of stealing your stuff than using these exploits. and as i said above wallets like Electrum don't just leave your secrets in the cash. it is flushed each time you finish up using them like after you signed your transaction. and will require to be loaded again in your memory which then requires password.Thats basically the reason why you can't just steal the stuff when having physical access. People plugging in an usb device to get malware on your pc waiting to gather your sensitive information is definetly a possible attack vector (if the amount stored is high enough). You'd only need to have access to the pc 2 times (before a TX is being signed on this PC and afterwards). This option shouldn't be underestimated if a big amount of money is stored. The meltdown vulnerability can only be exploited on Intel cpu's (those manufactured since 1995 (excluding Itanium and Atom chips made before 2013).
it can also be used on other CPUs (AMD) with a little modification. The meltdown vulnerability is exclusive to Intel processors (and 1 ARM core: ARM Cortex-A75), while the Spectre vulnerability can affect Intel, AMD, and ARM processors. 3 further ARM cores are vulnerable to a modified version of meltdown (Cortex-A15, Cortex-A57, Cortex-A72). But AMD is not affected by meltdown at all due to a different architecture.

If the Nano S doesn't let you do that, you may have to look at getting or deriving the private keys from the 3 addresses used for inputs on the transaction.
The nano s is just a hardware device which lets you sign transactions by pushing buttons. If something doesn't let you do that, its because of the wallet client used (in most cases: ledgers chrome app). I don't know any other way to cancel, I read that after about 2-3 weeks it disappears on its own, but it doesn't seem to be the case.
The reference value is 14 days. But every node decides how long he keeps transactions in the mempool. If a different node (or maybe your wallet) is rebroadcasting your transaction it might never get dropped from the network. Is there any way I can make it disappear on my own?
Unfortunately, no. You can't make other nodes forget about something. There are 2 scenarios where transactions 'disappear': 1) When a conflicting transaction has been included into a block, the TX will be dropped 2) 'all nodes' (or better: the nodes which are 'important' to you) drop your TX for any reason (e.g. not confirmed 14+ days) The easier way to solve your problem would be to get your TX through, instead of trying to abandon it. I would suggest you to do a child-pays-for-parent. This works as long you control at least one output of your transaction (most likely your change from the TX). You can use your nano s with electrum ( https://electrum.org/#download). Electrum lets you choose specific 'coins' to send from. From your addresses tab you need to choose the change address from your unconfirmed TX and right click -> 'spend from'. Afterwards send your coins to an address of yourself and include a fee which is high enoug to cover both of your transactions fee. To get an estimation you can visit https://estimatefee.com/. This way you don't need to import your seed phrase into another wallet (as mentioned earlier by others). With 'just connecting' your nano s to electrum your seed still stays safe and you will have to confirm the TX on your device. Afterwards you can uninstall electrum (if you wish) and you don't have to consider your seed as compromised because it never left your device. |

So if I am using a second PC offline which signs the messages there shouldn't be an issue?
This vulnerability still can be exploited. It just can't get remote exploited via the internet. Someone knocking you out (or walking to your pc, plugging an usb stick in and out) and using this vulnerability is (theoretically) still an option. But what if that offline PC is also running an Intel CPU?
Look above. Meltdown and spectre are two seperate vulnerabilities. The meltdown vulnerability can only be exploited on Intel cpu's (those manufactured since 1995 (excluding Itanium and Atom chips made before 2013). The spectre vulnerability addresses all modern cpu's (including Intel, AMD and ARM) and is harder to exploit/mitigate. You can read into both of the paper here: https://meltdownattack.com/ Can it somehow send private data by the QR code right after it signs the transction?
Could you please clarify what you exactly mean? You can't send data via QR. QR-codes are just a visualisation of data. |

I can view my BCH on my ledger (strangely, I have to have the bitcoin ledger app selected on the device, NOT the bitcoin cash one) using the Chrome bitcoin/cash/gold chrome app.
Since BTC and BCH share the same instance of the chrome application you can access(viewing history/recieve-tab, not sending/signing messages) both chains, but only interact (signing message/transactions) with the chain corresponding to your app opened on the nano s. This does not apply to BTG (having it's own instance). When I try to send, I get the error message: Sending failed. An error occurred. Please try again later.
This most certainly is the case because you didn't open the BCH app on your nano s, there not having any permission to sign messages/tx's. Open the ledger manager application and download the BCH app onto your nano s. It also might be possible that 1) the ledger service is under heavy load, not being able to answer everyones query or 2) a firewall (or any other program) on your PC is currently blocking the connection to the ledger server. Note: You can always uninstall/reinstall applications if you'r nano s is out of memory. Your coins won't get lost. After reinstalling an app again you immediately have access to all af your accounts/coins. |

This is (most probably) just a network/display issue. Did you already try to hit the refresh button several times (5+)? Sometimes this resolves the display bug. You could also try to delete the cache of your chrome app: Settings -> Tools -> Reset application dataIf this doesn't work out, reinstalling the chrome app is probably the last thing you can do. If that doesn't work ledgers server are probably having an issue atm (or your connection to them is broken). Additionally you could use a block explorer[1] to check the balance of one of your addresses (as long you remember / can find an address used) to make sure your coins are still stored safely and are untouched.
