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 .
