For me we should just stop. There would nothing be good coming out of people chasing their losses, there is a greater chance that you will lose than win all those back. There have been countless stories talking about these situations when they tried chasing their losses and miserably failed to do so. They all ended up with more debts than money.
Yes. To begin with, gambling should be taken as an entertaining activity that can sometimes give you extra money, not as the solution to your financial problems.
When people think about winning back what they have lost is either because they are playing emotionally or because they have lost too much. In both cases, the best thing you can do is to acknowledge the situation, and take some time to cool off.
