You need a profitable source and a method to gamble which suits you.
Mine is sports-betting. ;P
What do you mean by that? I think all gambling is just the same, and I dont think there is profitable source because it is depends on yourself when you are gambling and method? Is there any method on gambling? All game is just the same on how you doing it
People do well on sports betting and can make a living. There is a guy who made the WSOP final table this year who was originally a poker professional but was making more from sports betting so he quit poker full time for that.
But I guess that is one in a million that have that kind of luck and skill to play it because this is gambling sometimes you win and sometimes you lose. So there is no guarantee that you will end up to be rich just from gambling thing
