I sent 990 usdt for convert BTC. As far as I know, you need to go through KYC to exchange more than 100 euro worth of coins on a single day. Did you do that? |

I've found private keys with Iancoleman, but the address I found there starts with "2". However, my addresses in Coinomi start with "btx1q". When I lookup the receiving transactions on https://chainz.cryptoid.info/btx, it shows one address that indeed starts with btx1q, but the other 2 start with wkh_. I'm kinda clueless how to find the correct addresses using Iancoleman now. Bitcoin 1bc... Bitcore btx... Thanks for this, I've found the addresses as shown in Coinomi through IanColeman's site (although the start and end are different): IanColeman gives this address: bitcore1 q72a8qwj3uknxe8a33mfj3edejnhlsfprwydh8q Coinomi gives this address: btx1 q72a8qwj3uknxe8a33mfj3edejnhlsfprn2mz3y So IanColeman uses the wrong prefix which leads to an incorrect checksum. If anyone wants to report this (through Github?): feel free to  According to the block explorer when I follow the transaction link in Coinomi, some addresses start with wkh_. See this example. Coinomi shows the correct address starting with btx1q. Is this a bug in the explorer website? I've always had a very hard time installing the full BitCore wallet on Linux. Yesterday I tried the Windows version using Wine, and this worked without problems. The privkeys as produced by IanColeman restored the correct addresses, even though the Blockchain Explorer shows Invalid address. |

I tried to make a graph of all data extrapolated from 48 hour earlier data, then compared to the actual results. But my spreadsheet just can't paste a quarter million lines, so I gave up for now.

Bandwidth speed won't usually be the bottleneck because from my experience the downloads are done in bursts of a few megabits/second, and my node has a 1Gbps line.
Server processors such as Intel Xeons are usually good for sustained CPU activity but when running an intense single-threaded task like syncing I'd say "it depends": I've seen my bandwidth maxed out during the first part of syncing, and I've seen my CPU-cores maxed out later on. I'm pretty sure Bitcoin Core does multithreading. If you fixed one bottleneck, something else becomes the new bottleneck. My node has 16GB of RAM although I have almost never seen Core use more than 2GB at once. It won't use it on it's own, unless you manuall increase dbcache. |

Now that I'm done, I'll create a very short overview of how I would approach this if I'd have to do it again: Getting Forkcoins out of multisigInstall Electrum on an offline system, running from a LIVE Linux DVD. Restore the 2FA wallet by creating a new wallet from your mnemonic, but choose to Disable 2FA. Click File > Save a copy. Open this text file in an editor. It'll give you 3 xpubs and 2 xprivs. This is what you need, but keep the xprivs offline! Install a VM on your online system, install Electron Cash in there. Create a new wallet, select Multi-signature, choose 3 cosigners and 2 signatures. Import the 3 xpubs (NOT the xprivs!). This should give you a read-only wallet with the balance. Create a legacy Bitcoin address any way you want. Make sure this is secure, preferably offline and air-gapped. Keep this! Create a transaction from Electron Cash (your online watch-only wallet). Send all funds to your legacy wallet. If all funds exist on all chains (so your Bitcoins were all older than August 1, 2017), the lack of replay transaction means this transaction is also valid for BSV and BCH-A. Click Preview, copy the transaction. Use a QR-code or USB-stick to copy it to your offline system. On your offline system, install Electron Cash. Create a new multisig wallet. But this time it should be able to sign transactions, so use the 2 xprivs and the third xpub. Open the unsigned transaction in your offline Electron Cash, sign it, and copy it again. Use your online Electron Cash to broadcast the transaction. Pray a bit, and calm your nerves  Check https://blockchair.com/bitcoin-cash/address/1addy, https://blockchair.com/bitcoin-sv/address/1addy and https://blockchair.com/bitcoin-abc/address/1addy. If all went well, all funds on all chains should have moved from your multisig address to the legacy address on their respective chains. Get some Forkcoin dust that only exists on one of the chains to ensure replay protection on all chains. If not all Forkcoins moved, you'll need to manually get them out of multisig again. Use your favourite wallet for each Forkcoin to import the address (read-only) and create an unsigned transaction sending the entire balance (use all inputs on that chain, including the Forkcoin dust for that specific chain) to a new address on that chain. Sign the transaction on an airgapped system, then broadcast it. Repeat this for all Forks, start with the most valuable Forkcoin. Bitcoin Gold and Bitcoin Diamond have replay protection, you'll need to get them out of multisig the hard way. BCD has a working Linux clone of Electrum, for BTG I used the Windows clone of Electrum using Wine. Disclaimer: use this at your own risk! Be sure to know what you're doing before doing it. When in doubt, don't do it. And don't hold me responsible, you and only you are responsible for following my advice. |

I have a small fortune I abandoned on binance as they effectively froze my withdrawals pending identity verification. That's unfortunate, because Binance is the first thing that came to mind for exchanging such an amount (without KYC). I'd even consider exchanging it by myself, but if the source of the coins is the reason you don't want to verify your frozen account, I'll run the same risk. For BCH, you can try many smal transactions using CoinPlaza (referral link in my Mobile signature) or FixedFloat. CoinPlaza allows up to 100 euro per day without KYC, I don't know the limit for FixedFloat. I wouldn't mind doing this (for a fee), but it's going to take a while (so the exchange rate may be different by then). For BSV, I haven't found a trusted exchange that accepts them. |

So, if I were to give you a loan... And I were to hold your collateral, you don't think that would constitute bad intentions? Honestly, that is not something that would bother me, as long as all obligations to me are followed. In my opinion: - This is misleading because you charge for a service you're not providing. (I think we can all agree on that)
- Apart from the fee, the escrow isn't used because of being a third party, but because of having a trusted reputation. If the deal would be with the escrow directly, the other party likely wouldn't require an escrow. (I'm not sure if we can all agree on this one)
- There isn't any more risk than any other deal in which the escrow deals with 2 real parties instead of his own alt and someone else. (I think violating this deal would be the same risk and result in the same reputation damage as violating a deal with 2 other parties)
And this is mostly speculation but I wasn't arround at the time: did QS escrow this deal because he didn't want his alt to become known? AKA the main reason to do this was to secure his account farming at the time? Or did he knowingly suggest himself as an escrow to mislead the other party in pretending they are different people? |

This may sound far fetched but it is possible that this particular clipboard hijacker is using a vanity address generator under the hood to generate an address that starts with the same couple of characters That's not far fetched, it's quite likely. Either that, or it has a list of pre-created addresses. Or maybe it connects to a server to fetch a fresh address as needed. Not necessarily. Search can start from a fixed hard-coded key That would mean you can extract that hard-coded key and recover your funds (and funds of other victims too). Given that the funds haven't moved, it doesn't look like the attacker is in a rush to secure the funds.
I made a topic about this last year: How to lose your Bitcoins with CTRL-C CTRL-V. |

Hello, a few years ago we had a problem with the Electrum wallet, for a while we have entered Electrum with the seed provided initially, but when downloading the wallet on another PC and entering our data, the transactions have disappeared, as if nothing had existed there .
At the beginning we thought it was a Bitcoin theft, but we have verified that the address on the blockchain has the same value as we had. I don't know why but this is the third topic I've seen on a similar problem today. A suggestion I read is that your seed might be 2FA. So try to create a new Electrum wallet, choose 2FA, and import the seed. See if that recovers the funds. |

it just has got 9% of the blockchain in total. why is this slow as hell? From what I've seen you can improve performance by: - Using SSD instead of HDD
- Having 16 GB RAM
- Setting dbcache (database cache) to 4096
- Using Linux instead of Windows (I've never tested Windows myself)
- Having a fast CPU if that becomes the new bottleneck
- Enough bandwidth tot download 350 GB in a few hours

The Currency Exchange board is meant for selling and buying BTC for fiat currency. Interesting, that wasn't clear to me at all! I can imagine that was used in 2011, long before there were decent exchanges, but nowadays I consider all those just scam attempts. I've seen so many topics like "selling 1000 Bitcoin per day" in broken English. It's always "for a client". I always consider those scammers who are very happy to earn $100, and the responses they get are from similar scammers who also try to make a few bucks. Or, if you do meet in person, you'll find a $5 wrench. Like this: I am a physical cash buyer and will do transactions of over 250k EUR. I have a client that wants to sell 500 BTC asap! Are there still people who really use the Currency exchange board to buy or sell Bitcoin for fiat? |

Edit: I reported your post and asked moderators to move that. Let's see what will happen. Let's play ping pong between boards because it was just how he interpreted the rule. I don't think the rule (and that is assuming a sticky thread means something) can be interpreted any other way than " the trade involves bitcoin". TBH I also see it fits in altcoin board.
I'm saying this because you want to sell altcoins. Fair enough, you want btc for them but the idea of the thread is the sale of some alts. So if I'd change the title to "Wanting to buy: Bitcoin LN for Forkcoin dust" it would be okay? Or maybe even to: "Buy Forkcoin dust", similar to Buy Investment Gold, Have 180% paypal or WTS BTC for Neteller. The only thing we can do here is just agree to disagree, and there's nothing else that can be done. I can agree to that |

I believe I have reported enough posts, and have contributed enough (look at my merit) to have a lower wait time. Me too, but I don't expect it to happen. I've felt the 4 second limit for years  |

Yesterday, I created a topic on the Currency exchange board. The Currency Exchange rules state: 1. Altcoin (LTC, NMC, FTC, etc.) trades belong in Marketplace (Altcoins). However, if the trade involves bitcoin (ie. Buying Bitcoins and cows), it can stay. I've seen many topics selling or buying altcoins for Bitcoin on that board. I'm selling Forkcoin dust for Bitcoin on the Lightning Network: I will only accept Bitcoin LN payments for this exchange. My topic was moved to Marketplace (Altcoins). So either a Mod made a mistake, or Bitcoin LN is considered an altcoin on Bitcointalk. I'd like to know which scenario is correct. |

One scenario I imagine is if you split your seed into three to store as 2 of 3 factors of authentication, in case of 24 words, attacker would have to crack more words if they get their hands on one copy versus if you were using 12 words. That isn't really 2 of 3 FA since you need the entire seed to use the keys so it'll be theoretically more like 3 of 3. shows how this works: Sample Mnemonic: rule rent thrive soap worry issue east stomach suffer target flame annual unaware wool banner pole flavor limb divorce volume shell they gesture chronic BIP39 Split Mnemonic: Card 1: rule XXXX thrive soap XXXX XXXX east stomach suffer target flame XXXX XXXX XXXX XXXX pole flavor limb divorce volume XXXX they gesture chronic
Card 2: XXXX rent thrive soap worry issue XXXX stomach suffer XXXX XXXX annual unaware wool banner pole XXXX limb divorce volume shell XXXX XXXX XXXX
Card 3: rule rent XXXX XXXX worry issue east XXXX XXXX target flame annual unaware wool banner XXXX flavor XXXX XXXX XXXX shell they gesture chronic It says: " Time to hack with only one card: 3830854 years". A thief will need at least 2 cards to restore it. And so do you. You need 2 out of 3 cards to restore the seed. If you'd do the same with 12 words, it shows: " Time to hack with only one card: 109 seconds". |

Wow, that would be a breakthrough to put spammer out of works faster. Not really  |
