I believe that they are many people that are making money through gambling and we are not all losing in it. I have had from someone here that he makes about 50bitcoin from gambling in 2018 and I also have seeing many people complaining on how much they have lose in gambling.
I have not even heard about such won amounts. And I can not believe these numbers. More often it is possible to hear that people lose in gambling. Therefore, if you managed to win, then you need to stop and exit the game.
I've come across even bigger wins on gambling. The biggest win that I came across is the winning on bitdice casino. Here the player wagered in terms of 50,100 bitcoin. This is quite a risky try because what has been placed on betting is big. But that guy earned 350+ bitcoin including the bet amount. Gambling isn't a way to loss until you've got some good luck with you.
