It is not wrong as long as you are not addicted or something.
If you are playing for fun, not to earn, then you should have some great time by gambling, but if you are doing that as a "job" or as a way to earn money then it is dangerous and you should stop that.
Always keep in your mind that the only way to make money gambling is not to gamble.
ofcourse it is not wrong . but when you bet your btc or money in gambling site than it is wrong .
so i think everyone should away from the gambling .
well i am now after a small loss ( big loss for me ) i am betting with free satoshi gotted by capatcha at that site .
But without spending our bitcoins, we will not be able to gamble, moreover spending bitcoin will not make gambling wrong but keep on spending bitcoins among many losses definitely would be the wrong thing still gambling is not wrong but the gamblers go wrong.
Staying away from gambling will protect us from not doing the wrong thing but no one is ready to stay away from gambling because the wrong thing is more enjoyable for them.
