However i am a bet suspicious cuz as shown from his transactions he withdrew about 25 btc $232,174.87 in the last 2-3 days.
It is quite possible a glitch was found by OP and he was cashing it in small numbers, today he went for the big play.
Lets be serious, how often do we see a single guy win 25 btc $232,174.87 in 3 days on slots and then hit 171 btc $1,588,076.13 too ? come on now..
However this is the pessimist in me talking!
