Dont gamble at all if you only intend to play for fun. Why would you do so when you can just download most casino game in your smartphone? you can play those game without even risking a penny at all. Dont even think of doing it for fun because it is not fun to risk your money and dont want to get anything like that
Gambling isn't just for profiting only, we can't stop people if they want to gamble for fun.
There are two things with them:
It's either they are already rich and just looking to have some fun.
And the other one is they are just looking for something to do for killing their boredom.
No matter what status we are currently in life, we should above - to only gamble to kill some time and to have fun - nothing more, nothing less. Because we really take gambling as our source of income, we tend to become more prone to loss and extreme stress - which even if we win some, it won't buy the stress we are experiencing.
