Then there is one indicator that you can use for measurement - deposit/withdrawal. Because it does not matter if you win 100 times, when you can withdraw less than deposited. But what is the point of tracking such info? And this indicator turns to be useless for people who deposit to have fun. They pay for fun and they dont care if there is anything left on the balance by the end of a day. As for me, when deposit = spend, as well as lose = spend, such tracking makes no use. I dont measure my gambling as profitable or not, I measure it with I had enough fun or not yet.
for gamblers who don't care about such tracking of course it will not affect the gambler. but if there are gamblers who care about such tracking, I'm sure there will still be more in their accounts that they deposited than they withdrew.
there may be regret when they see these results, gamblers will think they should hold onto their assets rather than risk them. and the results must have made them happy.
but gamblers definitely can't be like that. most of them bet and then forget everything. it is not very important to look at the history of how many assets they have deposited or how much they have withdrawn.
