You should never gamble or bet if your state is not complete mental balance. I understand that this is trivial, but unfortunately our human psychology works in such a way that we want to quickly fix a bad situation by any means.
We hate stress and want to get out of it so quickly that it turns off our logic. As a simple example, I will give the fact that some gamblers, when they see that their deposit in the casino is decreasing, immediately begin to increase the beta value.
But is this the right tactic? Hardly.
