Doing this could help nothing aside from causing disappointment or frustration to the gambler. If we are in a business this is necessary to track where it is going but in gambling, we are just tracking how much we lose which is absolutely some kind of wasting our time and the result is just getting mad. That is a crazy reason for this and I can't imagine someone making this for that seek in the end they only find out that she/he is losing millions while just winning hundreds.
