I do not have any experience regarding the gambling of bitcoin but from the word itself, it has some similarities with various gambling games, which, I have an experience and poker and such. It depends on your luck, there will be times that you will win, but the odds are not always in your favor. It's part of the game- to lose as well. Just take risk and the best way is to set aside what is for the bet and what is for the play safe. You may not want to lose it all, even if there is a probability that you will win.
