Do you have a Binance account? Did you ever transferred there some coins? Is this transfer in your wallet transactions list? It's the RPtVVaPqstQeXNYfEb32YfAibsQ4YcueVr on your wallet sending addresses list?
To clarify the situation I suggest you to contact Binance (https://www.binance.com/en) asking about this transfer. I am almost sure their have a lot of logs. When I transfer something to Binance provided addresses (in general it's a fixed address per user, as ...Vr looks) they know a lot about the sender (including email address). So I think it's a good idea to ask Binance.
Thanks for the help. Binance has never done anything on the exchange. There is no account there. I'll try to contact them. I see all my transfers through the blockchain.
Huh? I am pretty sure chances are low to recover those coins. If a hacker transfers those coins to Binance it is very unlikely he leaves any trace. Most likely sold for some privacy coin and bye bye...
Deserve to try if someone lost the coins due hackers. I am sure all transactions are full traceable, including the 'anonymous' transactions. if there was a thief, it's just a matter of time locate the thief.
