I Deposited 3 times then after several hours of playing I doubled my bitcoin then after 1 day I lose all my bitcoin. I disappointed to lose all my bitcoin and I created new strategy to win but didn't work and I lose my interest in freebitco.in and I think my brain I lose too. Tell me ... how to win in betting?
It isn't self-evident. Take your time to learn:
"play more random than the random function that they use, don't follow any scheme" and look at
"variable house edge".
