It all depends on the gambler involved in this kind of situation, making gambling as a source of income isn't bad at all as long as the gambler can always sought a means out for himself everytime
For people not to make gambling as a source of income is like a means of telling people how risky gambling is. I do tell people that they should not reply on gambling at all, that they should even be very careful about it. Not only gambling, but also in trading. These two things are very risky, they can turn a rich person to a poor person is just few hours to days. People need to be careful.
Someone can decide to take just 5% of his weekly income to gamble weekly, that is not be. I do advice people not to use more than 5% of their weekly income to gamble weekly. But that he not stop me from saying that people should not make gambling as a source of income because I always think it is good for people to know that, which is actually the truth. Gambling should just be for fun Nd nothing else.
