Yes, it is always good to quit the gambling because if you are continously loosing through gambling it is good quit the gambling. Once you quit the gambling better dont reconsider it because you might loose more money.
Don't quit gambling completely if someone still wants to make money from gambling he can simply invest in the sites bankroll there are really profitable i had earned 0.1 bitcoin from all my investments in different gambling else you can trade also to increase your profit
O brother for god sake, dont smoke out people with wrong statements and ideas. Who said gambling is the better way to earn money? Do you really think it is? If it is, you must review your knowledge and mental level because only foolish people can say this. A totally lucky game cant be source of income for anyone. So kindly dont spread just wrong doings because this may harm someone.
The best way I think is to trade in bitcoin besides investing in gambling sites, because gambling is worse thing although you have made some money in gambling sites but on the whole it is not good and one day you can lose all your earnings and investment. If you have trade experience then you should invest in trading because you family will survive after you.
