What a bummer man that's a lot of coins gone. Gambling isn't for the faint hearted and only 1% of players actually win.
That statistic is actually bullshit, just saying.
I wount even touch the topic of how smart is it to play -ev games like dice, but keeping your entire roll on the gambling site (or exchange, for that matter), is not super smart as well.
Yup and makin bets of size of your bankroll is not a good move. Sorry for your loss Watoshi.
