It's like you can win an easy win once in a blue moon. But there are times that gamblers will win an instant easy win but it will be recovered again when they gamble and will be losing from their bets. This is the life in gambling, the path is really unreliable and no one can tell you a definite way of winning with an easy way.
When you get lucky and win big, stop - that is the key there. Because if you still play on and become greedy, you will eventually lose as the house edge advantage will going to play against you sooner or later but it will come.
It's good to play for some more and ask for better amount but make sure you had the profit then. We will lose if we will not be wise with our decisions to make with gambling. And you've got the easiest profit from gambling don't forget too that you can have also the easiest way of losing.
Just like what other gamblers were doing, they made profit instantly upon betting and earning good rewards but i resulted to failure and lose their investments. Even if you have to be assured of the profit you can't be certain of the betting results, and yet no analysis can predict those possibilities of your winnings. If you wanted to take that profit that you instantly win, you should stop immediately after you got the price of your bets so you can take that profit in an instance.
for short term only or temporary success. Treat it as an entertainment and look on the other side as there are more legitimate ways to earn there.
