You can't predict result, you can play for 1 year without stopping and still you won't be able to predict result of the game. No one has capability to predict anything in gambling, game is based on luck ffs.
Smart gambler is a myth.
Lol. That comment made me laugh. xP If you can do that maybe you can predict danger and things like that so you won't get hurt or killed easily. You can be a super hero or something. Mr predicto !! You won't be allowed in casinos though. Even if you can too the scale slightly you will be in the winnings. But you can't. So don't try.
Maybe being careful with how you spend bitcoins gambling is a "smart" gamble.
