If some of the gamblers are here only for fun and entertainment that means, this type of gambler is willing to take risk and can afford to lose, it doesn't matter for if He win or lose. But if you are here in the gambling to earn a lot, you need to have a good plan or strategy to beat the beat the house edge something like that based on my experienced.
There are only few that really understand gambling most of them are treating gambling as a easy to become rich and thats the reason why they are risking almost everything just to attain that goal.
But without realization that if they Save all the money they spend in gambling?i'm sure they are already richer than what they are now.
