Dave from http://walletrecoveryservices.com did a great job! A few years ago I lost my login details from my wallet on blockchain.com. Dave made sure I got everything back. And he has, very nicely, calculated the agreed 20%. And that, while he had the power to grab the whole bitcoin amount. It took a while. But I have 80% percent of my bitcoin back. And that while I thought I would have nothing. Dave is a hero. And also helped me super well with all the extra questions I asked.

Thanks Dave!
