I do multi-bets and single-bets, every time I win, sometimes I forget myself and use all my $$ on the next bet. This sometimes gives me big wins, but if I'm unlucky I can lose all my funds and this has happened many times.
This means that you are greedy. Do not mind me that I said that. I was like this before. I can win 10x and still continue to bet with the total money that I have and my winning together on a single bet. I even remember a time that I bet like $1 up to when I won $35 and I lost all at ones. It is called greediness and it happens to addicted gamblers. You will need to stop that because you are chasing money and not fun.
There should be a limit to how far you go when gambling most especially when you get lucky to win your First games, this is very important in other to save your winning and even your deposits, because regardless of how much you deposit into you account if you continue to bet along your line of greed you tend to lose almost everything because at that stance there is no amount that can satisfy you since you already have a jackpot in mind.
