it's for fun, when i have a lot of BTC. then it's for profit when i have a little BTC 
Hahah, gambling is indeed very pleasing to us. But if we are wrong to use gambling indeed we will get a very deep sadness. Gambling is not a place for profit, but gambling for fun. Only a small fraction that can benefit in gambling
According to me we actually are addicted to the feeling we get when we win, its happiness or fun Idk. But most of us call that as a fun.
so no matter what we say I think each one of us gamble for profit.
