Every gambler must set a winning limit to cash out winnings, if that is not done usually the balance will be drained again and end up continuing the game until it loses completely. I have applied both options and it feels annoying not to withdraw winnings early after reaching 2x what has been deposited.
Even emotionally we find it difficult to control to withdraw winnings first after reaching multiples of the deposit. This usually happens to gamblers because we think we can double it more on the next bet even though in fact sometimes we lose all capital or winnings from before. Every gambler does set a winning limit to be withdrawn, but we find it difficult to realize it under certain conditions.
For example we have collected $200 from previous wins and at the same time there is a match hat might make us place bets again. It goes on as usual because we find it difficult to create a consistent pattern on the limits that we consider appropriate.
