      Unfortunately, I can't. The platform was entirely fake, and since Bitcoin transactions are irreversible, there's no way that myself or anyone else can retrieve the coins from the scammer's wallet address. Be very wary of anyone claiming they can, because recovery scams are very common and many people fall victim twice. You'll have to take the loss, sadly, as there's no way to reverse Bitcoin transactions.

      Hrm, it seems it's pretty hard to do depending on the number of missing words. Each word adds about 11 bits of information you'd have to brute force, so above 2-3 words is going to be very difficult and resource intensive.

    Firstly thank you for the tutorial. 👍 Secondly, I have followed your tutorial and wanted to ask what would be a cause for the electron cash wallet show a balance as 0 BCH after importing the private keys?

    • @chaintuts
      @chaintuts Год назад

      I would double check and make sure you have the right keys. Usually that means you're importing the wrong private key or seed phrase for the wallet. For example, you've accidentally imported a key from the sending wallet, not the receiving wallet. For example if you sent from Exodus to Ledger, you have to have the Ledger seed/keys for this to work. A lot of people mistakenly grab the Exodus seed but it won't help at all in that case.

      @@chaintuts Thank you for taking time to respond. For context: I sent BCH from an exchange to my ledgers BTC account roughly 1 year ago and only noticed the mistake a few days ago. Actions: opened BIP39, input the ledger 24 word seed phrase, changed from BIP44 to BIP89 as per the ledgers BTC address, located the corresponding transaction and BTC wallet address, copied the private keys from BIP39 into the Electroncash app exactly as shown in your video. Once complete the electroncash account shows a zero balance against that private key. Have I missed something?

      @@chaintuts it is a BC1 address.

    • @chaintuts
      @chaintuts 11 месяцев назад

      Unfortunately in that case, you probably can't recover. Bitcoin Cash (BCH) doesn't have compatibility with native segwit addresses (bc1) or segwit addresses (3). 3 addresses are still considered "valid" by the BCH network because they are used for multisignature addresses, which are different "under the hood" than segwit. I'm not sure why sending to a bc1 address even worked on the BCH network. But either way, sadly, there's not currently a way to recover coins sent to segwit addresses on BCH.

    Underestimating Ai and quantum processors

    • @chaintuts
      @chaintuts Год назад

      It only matters sometimes...SHA-256 and RIPEMD (hashing functions involved in Bitcoin) aren't any more vulnerable to quantum. So for an address that hasn't been spent from, the crack time would be the same. For addresses where the pubkey is revealed, ECDSA is somewhat vulnerable to quantum. Hence the push for Schnorr signatures and other signature algorithms :) Very interesting stuff.

      Hi LK, yes this should work in reverse, especially since BTC supports legacy 1 addresses that BCH uses. In order to recover, you must have the private key/seed for the *receiving* wallet, not the sender. So if you sent from Coinbase Wallet to Exodus (etc.) that has a seed, you can try these steps. If you sent to an exchange wallet, unfortunately you're out of luck. I do some consulting for possible cases for a fee.

    They have every excuse in the book to try tricking me both on Facebook and Instagram. It's how the conversations start that gives their illegal conduct away. Usually if they start off with something like "Hello, how are you doing today?" I already know it's fake because most people will say your name if they start off with hello. Like "Hello Josh how are you? vs Hello how are you (meaning I don't know your name) etc. Another one is just straight up starting a conversation with a person by saying "Can you please vote for me?" Or "Hey can you do me a favor? Can you tell me your phone number so I can log back into my account and tell me what the reset link code is?" Like these people really think they're gonna trick me into taking over my page. They try so hard to do it too. I tell them bogus names and then if I don't respond they ask me if I got their link or not. One story I gave the most recent one was that I had a girlfriend who would send him/her the scam link. I told them her name is Jenny and her phone number was 555-867-5309. The dumb *** actually believed me. Like they act like we are gullible but then we turn around and return their stupidity ten fold without them being "smart" enough to know they're being played 😂😂

    Another great video Josh. It is unfortunate that so many people just don't realize how critical some pieces of information are, like a 2FA code, a password reset link, or a crypto wallet seed phrase. I'm not really faulting them because, if you are not at least somewhat of a tech person or haven't taken the time to learn about them, some of these things can be very foreign concepts. I worked with a guy yesterday who was newer in crypto. He had an issue with his wallet. Someone convinced him to put his seed phrase into a wallet confirmation site or something. Then his wallet was empty. Luckily, he only lost something like $22. I hate seeing those things happen to people, so I do my best to try to help people understand to never share information like that.

      Unfortunately, no. Cryptocurrency transactions are not reversible. In 99% of cases, the money is gone forever. You *absolutely* should report this to the police.

Anything less than that and it's not worth the significant cost of working with a PI + police.

      They are both fake. Pretty much any "recovery" service that claims they can reverse transactions through some technical means is a SCAM. The only legitimate recourse you have is to contact the police. There are 2 PI firms I know of, CipherBlade and CipherTrace, that provide legal assistance to the police (reports of where the coins went, such as exchanges). That's it. There's no way to "hack" back lost coins, and pretty much every recovery service is a scam.

      There is no way to recover the coins in this case - the money is lost. Binance is a custodial exchange - they don't give users access to the private keys and they generally don't help people recover coins sent to the wrong address. This is for security reasons, as no individual support agent would have access to the keys needed. I am sorry I cannot help you recover your lost coins, but I hope you have a good day otherwise and learn from this experience.
