You are right. As long as he can play gambling many times, I am sure he will get experience in gambling that will give him the chance to gather everything he wants to know. But we can give him suggestion not too long to playing gambling because he can become addicted to gambling and he will be difficult to leave gambling any times.
when you have found a good method and can guarantee profit for yourself when gambling it will be difficult to stop gambling because the flow is like that, gamblers will suffer losses at the beginning but luck will be easy to get because they already know the steps to get profit.
I am afraid I cannot found that method since I don't use my most time playing gambling. I don't see that even if I have a good method for playing gambling can guarantee me to win the games because I always know that getting winning in gambling will not easy. Many people are trying to win, but they will end by losing the money, and I don't want to be like them.
