yeah gambling is fun because there is a lot different games and we get entertainment from that and there is maximum people are on gambling for fun and some people are in gambling for earning more bitcoin.
but i think maximum number of people are playing gambling for making money and not for fun, they can only feel fun in gambling if they are making money and if they are not making money in gambling there there is no fun in gambling of they lose money.
losing money are indeed not fun at all , but for some people there still enjoying at certain game even they lost money it is mean nothing as they feel comfortable with the game , so no problem if they lost a couple bucks.
the problem in most gambler are when they lost too much money.
