my strategy gambling is marti
Never do martingale

It does not work!
I just tried it and lost 3 times in a row choosing the same color and side.
It is a retarded method and you will lose more than you win this way.
The casinos has counted on people to bet this way and they have the upper hand.
Actually martingale method work for some people so you can't say that it doesn't really work. By the way, martingale method is about patience since you'll need to wait for it to earn on it since you must only bet low amount so that it work.
It works but if you play longer period of time with it, you will eventually lost because of the house edge. There are also things you need to consider when applying martingale method and that is how much maximum profit a casino set. When you reach to that level, there is no other way you can double your bet because you reach the max cap of bet.
