What will you do with your last balance? Waiting for the right moment before made a bet or because I like sports betting sometimes I bet on the game that will end? i do that because no more chance for me so i think better i'm rely on luck.
I won't risk my last balance if most of my balance came into losing in gambling. What I do is to cultivate it and taking a better option of taking a risk in trading, it's a more reliable way of if you want to not lose that last balance of yours.
