This advice which I am giving right now is for rich traders. Like if you are tired making small small profits then there is a very good way to gamble and make ez profits with 10% loss chance. What you basically have to do is you need to set an amount and choose the colour which you come . Let me give you an example.
Say there are 3 colours  RED , BLACK and GREEN. Now if you place your bets on RED or BLACK and you win then you get double the amount you actually put in . And of you bet on green and you win then you get 14 times what you bet. But now let's ignore that green thing.

What my trick is you basically neet to set an amount to bet on REF or BLACK (depending on what you feel) and then go . If you win let the amount you bet be the same and then do the same thing again. But if you lose then double the bet and try the same colour again and again unless you don't win. And double the amount as many times as you lose. This way even if you win after losing 10 times , you will still have a 20 USD profit. Think over it . Like first you out 20 then you lose . Then double your bet and put 40 so if you win you get 80 and then subtract 60 (40 + 20) from it . Boom you made profit . But as stated above this is only for rich people who can deposit a huge amount to be on a safer side and make profit.
