You are right, this is important for every gambler to know if you are actually winning or losing... gamblers that don't keep track of their gambling activities are the ones that end up losing more and my reason for saying that is because if they can check deposits and withdrawals on a monthly basis they would be able to quickly adjust or make some changes when they figure out that they are I. Loss
Even if gambling is entertainment for you, I still think that statistics should be introduced, because it allows me to know the profit or loss for a period, for me it is also important, because it adds excitement. And maybe it will help someone to stop in time, if there was no habit of tracking their losses before. But I think that limits should be set for this, it will work much better.
