I do not have an experience to gambling.
But based on my understanding, it is not totally bad or wrong.
It depends to someone who plays it.
Thats the baaic form we can actually called for gambling and thats gambling is totally fine and i dont see either some wrong for it.
For legal aspect, if gambling is illegal in your country, so gambling is wrong. If not, it is not wrong.
For religion aspect, Christians and Muslims consider gambling is wrong.
Our government could be wrong on the other hand of making gambling illegal, they should make an exception for those who are not minors to play gambling because that is our privilege to enjoy and we take the full responsibility of our actions.
How could you think government is wrong For treating gambling as illegal? I do agree with them since gambling is destructable for those people who easily get addicted for these things and these is just a simple warnings since it can give bad effect to anyones life, and their are other syndicate whos making illegal underground gambling so theres nothing wrong for making it as a law or pointing it as illegal hobby.
