yeah nobody wants to set an specific amount of money to lose.
It is more lovely to say on how much money or what is the amount of bitcoin you tend to set at your maximum limit when playing gambling.
People who always set a limitation will definitely don't have a regrets at all every time they lose at the end.
But for me I had set my maximum amount to put at stake at gambling when I am playing at around 0.005 btc.
I Think That is a considerable amount to put at stake.
