hope can definitely be a poison in some situations
specially when you can't do anything in the situation to change and improve it
better to approach gambling in a less emotional state
just my two cents here
It can be bad when we are getting too ambitious on our each bet that we would win or seeing others we also hope to have high mutilpliers on our bet copying them but if we you are hoping that you could win if luck favours you then it's not a problem according to me but still you should be happy on each bet whether it's loss or win instead of getting into depressive state with your loss.
Betting is something that has no certainty, so if you are too ambitious to win, it will only end in disappointment, so betting is reasonable and you think of betting as a means to please yourself and yourself.
Maybe being able to get a multiplier is a pleasant fortune but it's not easy to get it.
It is true, as you said, that whatever the outcome of the bet, whether you win or lose, the gambler must accept it with pleasure.
But you also need to know that many gamblers cannot accept defeat, so they chase wins that they can't necessarily get.
