looks like your winning 4 times with max bets raised some flags. it's not the first time I've seen a gambling site ask gamblers for their information when they won a lot of money. anyway, are you sure you want to abandon $12k? that is a sizable amount of money(at least for me).
I have taken screenshots of every transaction in the site. I can upload everything.
I suggest posting them now to back up your claims.
I don't think he waited 72 h so i don't see any scam here.
Only reason he paranoid if he did something wrong like win using a bug or something.
Otherwise why can't he simply wait for 72h ? Also come to think about it 4 wins in a row with maximun bet is something unusual
