It is very difficult to continue playing when the winnings have already reached $250-500.
Keep the minds.
If we lose, we just lost 1$ from the originals bet size we are doing. Same way, my self..... i doing all in betting only with promotion or bonus balance. At least, if reached some amount money like 1 month salary. I just lose the bonus balance not deposit.
These kind of things, are being recommended only free money/bonus.
