Can you prove ownership of coins? I've seen too many mixers turn into a scam.
If you pm my main account (see signature) a signed message, I'll confirm you own 64 Bitcoin here in your thread without exposing your address.
Hello,
Thank you for your proposal but I don't force anyone to believe that I have 64 BTC,
Go ask the Mixer who say they have +500 BTC

Bests regards.
