Betting your bitcoins may result on a lose, you shouldnt gamble what you can't afford to lose.
If you plan to earn money using bitcoin do not gamble it, is the same as fiat, if you have money in hand will you go to the casino ?
if you are afraid to loss, then you must stay away from gambling because you can not win with easy especially if you don't have luck. but if you are only curious about how its feel when you are playing gambling then you can trying but you don't have to use big money. but be careful, don't playing gambling too much because you can be an addicting person and its too risky for you.
