I think more often than not the all-in bets make you lose your bankroll rather than save it, but there have surely been times especially in poker for me that I kept going all in even when I had practically nothing to lose and I came back and made a killing! My favorite game to do this one tho would definitely have to be roulette.
wouldn't it be very risky to lose it all when you decide to go All-in.
In one good moment, of course, it will give many benefits, but the risk will also be greater.
I didn't even have enough courage to do All this, even though it looked like a victory.
Doing management and leaving some money would be better as a backup.
Victory will not always come, there will be defeat that will also come to anyone.
