Some people gamble for fun which is the right reason someone should gamble. If you want money from gambling, let it be small in a way that you will still not use more than small amount of money to gamble. Do not gamble because you want to make money and be using high amount of money to gamble because gamblers are always losing than winning. The losses are so much more.
I have never believed in the idea of gambling for fun. If someone that gambles for fun experiences a losing streak like up to 20 straight losses, will the gambling still be fun for him? Even if the person gambles with what they can afford to lose, losses are losses and it will definitely show in the person's countenance.
So, the fun of gambling is the winning and losses also, that is why I believe there is a balance or there should be a balance in order to keep the gambler stable.
Op, the best way to gamble is not to expect to be suddenly rich with gambling. Just gamble like a normal human and not a addict that wants to turn 50 cent to $10,000
