The part where a gambler has to use just a small percentage of their money is a good strategy but in the aspect of targeting 1.5x - 5x profit is what I even don't archive most of the time because immediately the game starts, it can just crash even before getting to 2x. I played crash last week and I didn't make any profit from it.
You didn't win, but that does not mean you will not win again next time. One good thing about reducing the amount you play with even down to the lowest is that it gives you a better chance of trying over and over again before you exhaust what you have in your account.
Luck will definitely be on your side, because there is no way that you will try luck 10 times and it will crash down below the 2X multiplier. There is always a chance for you to regain all that has been lost only if the person doesn't get greedy when they see it flying.
