It can makes you cry in different ways. One way is that you cry because you won something like money etc.Other way is that you cry because you lose all your money and that is not good. It is always that you lose more money than you win some.
Indeed, gambling makes you mostly cry when the you lose and I think everyone loses sometimes with gambling is normal and nothing more than logical.
I once made the mistake to just bet with blackjack, I won 1 time and that was the second time and with the second time I lost it all in one bet...
Because gambling in truly risky and that is the proof right there when you lose it all in just 1 bet, I think you need to be very careful in playing it, when you win on your first bet, then just bet half of your win on the second so you still has the other half of your win then when you lose on that bet try to half it up again for the third and if you also lose then stop for a moment and think if you will still keep on playing or not, you should not bet an all out game on gambling because it is really risky.
