i don't do anything specific, but if you're playing slots or aviator-style games, i.e., if you're expecting high risk/high reward, increasing your bet amount is pointless.

if your balance is $100 and you're spinning $1 slots each time, it's likely that you'll increase your bet thinking you'll hit a big win at any moment. this is just a psychological mistake, because even though you know you'll almost never get a big win, you still think you might get it all at once.

other than that, increasing your bet in games like blackjack, roulette, or coin toss, where you win about half the time, is normal and acceptable.
