I’ve been on this situation many times before and I keep playing until I get the entertainment that I want and to have more profit. But the result is always ended up losing everything because it’s very easy to increase bet if you knew that your money that you use is a profit.
Even without raising the bet size, the result will be the same if you don't stop
As for doubling, this is nonsense, hardly anyone stops after such a small win. It seems to me that when people dream of winning, they want to get at least x10. x2 even to the entire deposit is very little to stop. By the way, it seems to me that slots are exactly the area where gamblers are waiting for huge winnings, something like x100-x1000 and they definitely won’t stop after x2.
