I think that if gambling platforms displayed the results of wins and losses over time for each user, similar to how exchanges do with futures, it would be useful for some gamblers. At least a user would be able to clearly see how much money he has lost over time, and that it's time to stop.
Wow this is a good move, I totally agree because I am also quite curious how much money I have lost from gambling but there might be a concern for the casino if they do that, where there is a possibility that many users will stop gambling completely from their place for one reason seeing that the money that has been lost is very large and it can reduce the casino income, who knows that just my opinion.
