I buy bitcoin to make regular profits from it by selling when price goes higher and sometimes I also buy to have fun in gambling with it.
I think it is better to trade alone than you do trade and gambling. maybe you'll get lucky in the trade but will be lost in gambling. its only waste time
You have a higher chance of losing money when gambling then trading.
i think many people like gambling for just entertainment, and if you want earn bitcoin then many ways to earn free bitcoin through bitcoin and through other online tasks.
Possibility of losing money in gambling is always possible but if you are just treating it as an entertainment then it is your choice if you are fine with losing your bitcoins in exchange of enjoying with those gambling sites. But still it is better to hold bitcoins and trade it if you are buying and hoping to get for some good amount of profit.
