Best strategy is this one!
1.Never gamble more than you can lose!
2.Never get greedy!
3.Set yourself a small goal!(let's win 0.02BTC)
4.After you win stop gambling!
5.Cash-out!
Does it work for me?
Hell YES! Until I get at number 4 and lose everything!
LOL
I think every one got crash on no.4
Or after no.5 adding you a no.6 Deposit and gamble again ...
