however I see a lot of my friends says "im stupid" and stuff like that , because they start earning a lot on the begining then they get greedy and lose basically all , does it happen to you ?
People who gamble should always be aware that what they're doing isn't a long term money maker. Especially if they play games where it seems like you can realistically have odds(PvP games,sportsbetting) a large number of people seems to think that the odds are in their favor because they think they are such good players even though the average house edges are way higher than in games like dice and the number of people who win money in the long run is incredibly small.
yes, gambling on dice is genrally not profitable in the long run, but in more predictable gambling such as sports betting, it can be profitable with hadicapping. It can also be profitable in the long run for more skill based gambling like poker, ive seen people at (real life) casinos that practically live there.
