how much should you bet on roulette with a $100 budget?

Every time I step up to the roulette wheel, I have to fight that urge to just put the whole budget down on red or black for that quick thrill. But with $100, that can disappear so fast if you hit a rough patch. I’ve tried splitting it up into $5 chips to give myself a decent number of spins, but then I get stuck debating if it’s better to spread out inside bets or just stick with outside for more consistency.

Does anyone else try to stretch $100 with a mix of patience and a few riskier plays in between? My friends think I’m too slow and want to go hard or go home, but I usually end up lasting a lot longer at the table and sometimes walk away with more than they do. Just curious how others pace themselves or if anyone has a set routine.
