The bankroll mistake that wipes out 90% of bettors (and it's not what you think)
Most bettors don't lose because their picks are bad. They lose because of how they size bets.
Here's the pattern I see constantly: someone hits 3 winners in a row, gets confident, and doubles their unit size on the next play. Then a normal, expected loss (which happens even at a 60% win rate) wipes out two days of gains in one shot.
The fix is boring but it works: flat unit sizing. Pick a unit size (1-2% of your bankroll) and don't touch it based on emotion. Let your win rate compound over volume, not over one lucky streak.
Some quick math to internalize: even at a 55% win rate against standard -110 odds, you're profitable long-term — but only if you survive the variance. A bettor sizing bets at 5% of bankroll will bust far more often than one sizing at 1%, even with the exact same picks.
I run Dream Hits Picks, a daily picks community across NBA/NFL/MLB/NHL, and bankroll discipline is the first thing we drill into every new member before we even talk about the picks themselves. The picks matter, but the sizing is what actually determines whether you're up or down in six months.
Curious what unit sizing everyone else here uses — drop it below.
