Your bankroll is your total betting stash.
Not your daily spend.
I use units (a % of your bankroll) this helps build long-term success and weather any bad streaks.
Here's a calculator so you know exactly your betting bankroll and unit size.
Losing streaks hit everyone (even sharp bettors). See how fast a higher unit % drains your bankroll vs. how a smaller unit rides out the wave.
Risking a unit keeps your exposure locked at exactly $100 per bet, no surprises. On a losing streak, your max loss per bet is always the same.
