I think i gamble for the same reason many other people gamble, for a chance of profit.
Most of us, we gamble for profit but at the same time we like to have fun as well, the entertainment that we experience is something that really makes us comes back to play from time to time, aside from being challenge on the game/s that we have been playing.
I also watch people on Bustabit winning & say "well this isn't too hard". Then when i try it, its extremely hard.
Well, that's the reality, it's easier to say than to do it and we can't deny the fact that majority of the gamblers loses money, that's the formula that would result to gambling sites being so profitable.
