Actually I've lost a large amount on gambling. I often spend some bitcoin which I deposited in gambling. But I gamble just to play, because I like to play like poker, sports betting and blackjack. It was very nice to me, and most importantly, a good self-control in order to avoid the greed that can result in huge losses.
It is always fine to be gambling because there is fun in here, we just have to control ourselves and always remember that we might lose everything we have if we will not accept defeat and continue to gamble, as a gambler the most important thing is we need to be smart to adjust our method and never gamble with our emotion.
heavy losses are indeed obtained from gambling that we do. If we do in a way that is not good or greedy then it will give bad impact to us, indeed sometimes that way gives good impact. but it only applies to 1 of 10000 people are doing it. so it's not like it's a chance we can get the easy way. It is better to play with calm and don't be greedy
