I gambled about .12 btc fairly low..compared to most.
But after I lost that over at primedice, I never want to feel that crappy feeling ever again.
It's normal for lose or win in gambling games, especially on a Dice game.
Just play for fun with amount that you can afford for lose.
If you want to try your luck next time, be sure to trying blackjack in Crypto-Games.net

Best Regards.
