Question for Steven Hay

Hi Steven,

Hope you don\’t mind me asking this directly to you. I\’ve an update on the problem we\’ve previously discussed of people who have sent BCH to a BTC segwit address, which i\’d really appreciate your opinion on.

First of all, btctroubadour updated his reddit post (the one you mentioned to me) to say the following: “It looks like some greyhat/vigilante, working with an unknown miner, was able to unilaterally claim some of the BCH that were “stuck” in BTC-segwit addresses (namely, the ones for which the public keys were revealed by the owners spending BTC from the same addresses), as explained in this post and comments: https://np.reddit.com/r/Bitcoin/comments/7eixcu/recovering_bch_sent_to_segwit_addresses/ For those that are affected by this, it means you no longer control your BCH (they were “stolen” by the greyhat), but he seems to be offering to give them back if you agree to letting him keep 30 % for his service (or “service”, however you look at it). Either way, and given the alternative (100 % loss), you should certainly check if you’re affected and decide how you want to proceed. As if that wasn’t enough to deal with, there seems to be a ~2 week deadline, until “December 5th, 2017 at 23:59:59 UTC”, after which it seems he’s decided he’s entitled to keep your money. :(”
It seems to me that if you have since spent any BTC from the address that you sent the BCH to, it’s likely this guy now has your BCH and will refund you 70% if you contact him with required details BEFORE 5th December. If you thought you had lost the coins, I guess getting 70% back is a positive. In my own case, I haven’t spent any BTC since I sent the BCH so I don’t think he will have my BCH. However there then comes a further update.
When following some more links from the original post, I found the following comment: “Have you sent Bitcoin Cash to a Bitcoin Segwit address? Worry not! http://BTC.com has got you covered! We are proud to announce our new Bitcoin Cash recovery service. Please send an email to [email protected] to begin the process.”
So I sent them an email and received a reply saying they need:
1) My wallet software
2) segwit address
3) Expected new BCH address
I would really appreciate your thoughts on this option. Do you think it’s legitimate? Is it safe to provide these details? Do you think following this process will result in getting my coins back or open myself up to having them stolen in a similar way to how the people in my previous point have done by the greyhat? If it is legit, do you think there be a “service fee” for this?

Kind regards,
Kevin

Hi Kevin,
 
Yes, I believe the BTC.com recovery service is legit. It only works for certain wallets however, so don’t get your hopes up.
 
I believe that sending the information you described should be safe. So long as you don’t give them the private keys to your wallet, I don’t see how they could steal your funds with only that info.
 
This certainly seems like a better approach than giving 30% to the greyhat. If BTC.com charge for this service, it’s sure to be far less than 30%. I’d say it’s definitely worth a shot, sorry that I wasn’t able to point you to this option from the beginning as I simply hadn’t heard of it.

Thanks very much Steven. I believe this service has only recently been made available and wasn’t an option when I posted my first question, so no worries about not mentioning it before. And I really appreciate your knowledge on this topic, i’ll proceed (hope it works with Trezor wallet) and let you know how it goes. I know there are many others who have had the same problem so if it works i’ll be telling everyone I can about it. 
Kind regards,
Kevin

Hi Steven,
I answered the 3 questions from btc.com and they sent me the following link – https://bch.btc.com/docs/help/bch_segwit_recovery
The good news is it seems this solution works for Trezor wallets and the service fee is only 10% instead of 30%. The not so good news is that it seems fairly complicated to perform and there are several opportunities to make a mistake.
I’m also concerned about details I have to disclose in order to do this. I’m thinking that maybe I should move all my funds from my Trezor wallet before doing this to ensure they are safe somewhere else, although that may leave me open to the Greyhat being able to “claim” my BCH because i’ll have made a transaction from my Bitcoin address and therefore made available the public key. 
Could you please let me know your thoughts on this?
Kind regards,
Kevin

Hi Steven,
Do you have any thoughts on my latest comment? I’m keen to try ro recover the coins, but wary of risking everything else in my wallet. 
Kind regards,
Kevin

Just a final update from me, I used the btc.com service and got back 90% of the coins. Very happy with this outcome as I thought i’d lost them forever. Thanks to Steven Hay and btctroubadour for their help on this topic.

Kind regards,
Kevin
