Even if you are master of prediction . You will loose sometime ..
1.01x doesnt mean you can profit all the time. I ever bet 0.1 with 1.02x and directly busted it all in dice game. Low odds doesnt guarantee you will always on profit sometimes you will lose it too before you can double your balance
If you really want to play safe on gamble, and really got profit from it. I know some good strategy.
First, you must watch the game play or at least you know about what you bet in (and this is only for sport bet)
Second, when you really believes some team will win or when the game almost over.
Bet on winner team, probably you only got odds @1.03
But it doesn't matter, you already got 3% from what you bet. And do not so sure to bet all-in with all your money/btc. Just bet fine amount for yourself.
