No gambling is "safe". Where there is money, there are always people scheming to snatch it from you. I had a career as a pro poker player in a former life, so I can't tell you that money can't be made. You need to be really, really good at it and then there is still the chance your luck will run out and you get clobbered. You always keep a bankroll in reserve; just in case.

If you enjoy the lifestyle of a professional gambler, you might make some money. But keep in mind that many try and fail. I would suggest you read the biographies of top gamblers like Stu Unger to get a feel for how their lives go. Here is a video documentary about Ungar:

all sites have a house edge some are low some are not but nothing is ever risk free

I think it is a stupid waste of bandwidth and human energy. Why not learn a skill that makes the world a better place instead of trying to get "rich" in some stupid online scheme?

because learning skills is not easy. and peoples here want to become rich in just one night. simple.

Why? Do you think rich = happy? I wish those people would go back to reddit.

well, I didn't come from riddit. what is reddit BTW? I don't find any earning ways on riddit/

From what I can tell, you have no skills worthy of earning anything but a dunce cap.
