First of all , i think that gambling on a small budget is a wrong thing to do since you'll be dragged to bet on high odds expecting quite huge winnings when you weren't even able to bet with high stakes , that will eventually make of you a greedy person and a greedy person is by default a bad gambler .
I think that one of the best pieces of advice to give to someone who is betting with a low budget is to make single bets and half of your money on that single bet , it'll be good returns with small risks , and if you loose you got the remaining half to compensate .
I think the best practice should be done with a gambler is stop after winning. Never be greedy so that you will not go home with regret. You must set up limitations for yourself all the time.
yes, this is a good practice that he can do after he can win the games. this will be difficult for him because if he can be a winner, he will be attracted to continue the games because he hears something in his ear that still ask to continue and he has another chance to win the money. and if he cannot stop after winning, then he will lose his winning money until he doesn't have any money again.
