I never counted, but I think I have much bigger losses than gains. It is not hard to conclude that, but the thing is I never had big expectations of gambling. Sometimes I try out the site I find on forum and sometimes I just play on sites I already tried.
I mostly set a limited budget that I am willing to gamble and then count the losses in the end. I don't gamble with expectations to earn money.
Do you know that everyone gambling gambles with expectations and of course they wouldn't reveal themselves they gamble with expectations. Expectations I mean is either to make additional money from gambling or to have fun, that is why there are people who go to gambling house today and if they don't have fun you would see them leaving the gambling house since their expectations or variety of games weren't there
