After the first win i think o most 95% of gamblers want to bet again because you have a feeling that you can continue the winning run for sure. I personally after a win never stop so maybe its a mistake but it gives you a huge boost that you can win big that day and in most cases that dosent happen
Because after they win they have the belief that today is a lucky day even if they continue the game again they are sure with a hunch that they will win --- do you experience something like this in a casino? Yes, sometimes we think that way without thinking that losing can happen at any time.
It would be natural that after winning they would not stop, instead playing again hoping the multiplier comes again to win --- but unfortunately it is usually a mistake that ends up being a big loss.
