Many users claim that they play for fun. At the same time, they do not hide the fact that all the money is lost one way or another, quickly or slowly. If you are losing money, then how can you enjoy it? I could never understand this.
If many people play gambling for fun, what's the problem with you? If you feel a different way, it indicates you don't use the same approach. But it doesn't mean you have the right to claim those people use the wrong way. People who gamble for fun, they surely use a small amount of money. They aren't very obsessed to chase the wins, they are trying to be more realistic. I think this is even safer for an individual, he/she has no way to gamble excessively. Is it bad thing? 
Your face looks different from mine, That tells you that we all were created to be unique in nature, what you don't enjoy doing, somebody somewhere enjoys doing it, what you think is stupid to do, somebody somewhere thinks that same thing is the best thing to do, it's personal opinions and different people choose to love and hate different things differently~
Agree. Each person may have a different perspective. There is nothing wrong to have a different opinion as long as it doesn't bring any harm. Those people who gamble for fun, they aren't stupid but they think a more realistically of the goal. They are aware that losses are something usual, so they don't think about it too much. We must assume that there should be the time for the wins in the future, too. But since it is uncertain, we prefer enjoy the process. Moreover if we like the gambling games. So why we don't enjoy the process, right?A gambler who enjoys gambling and does it for fun already know that there will always be loses most times, but from the onset have written off this loses not to be a problem, it's like programming your mind to believe that money you have is lost so that when to eventually lose it, you won't fell a thing because the money was already lost before you lost it, this is one way I really enjoy gambling for fun even in the midst of loses, and besides, those who gamble for fun do not stake high, but very tiny amounts of money that appear or they consider valueless to them.
Sure, playing for fun should be with a small amount of money. But everyone can have their own perspective about "small amount of money". I may say $100 is small amount, other may assume it is big amount. However, it should be the amount of money that we afford to lose.
