My gambling comes down to betting on football games... It's mostly the games I'm interested in... I bet for fun (to confirm my predictions), I have no goal to earn money... That's why I don't spend much time doing it and I am not addicted to gambling...
At least that's true because when you just want to see how accurate the predictions you have in betting, at least you don't have to spend a lot of money on betting. But, if the results are always good then I think there is nothing wrong for you to bet with higher money, because even though it's just for fun but if your predictions are always good and correct, then I think increasing the bet amount will be a good idea. Because then you will make your fun more profitable, right.
I don't know but gambling is kind a tricky, if you'll bet small amount of money just to see if your prediction is almost accurate, you'll win. But if you'll take it seriously like betting a large amount of money, you'll lose, which is pretty annoying. That is the reason why I only spend my spare money in gambling if ever I wanted to play gambling, because gambling isn't the one for me, I admitted that for a very long time ago that's why I didn't get addicted to it.
