It could be.  But Nakowa was different.  He didn't arrive immediately after a coding scandal that saw players record losses when they really won.  Nakowa also placed many bets at the full site profit right from the start.  200 btc bets were not unusual, and he would come and go instead of sitting in hours long sessions.

For all we know maybe mateo is a whale with thousands of bitcoins who is just playing for lolz.  But maybe not.
