A Guide To Bankroll Management For Sports Bettors

While the flashing lights of the casino floor attract millions, sports betting has exploded into a massive global industry.


Treating your betting funds like a professional investment portfolio is the only way to survive the long, grueling sports season.

The Concept of the 'Unit'

Professional sports bettors never talk about how many actual dollars they bet; instead, they exclusively use the term 'units'.


When a professional says they are up '5 units' for the week, it means their bankroll has grown by exactly 5%.

Even the best professional sports bettors in the world only win about 55% to 58% of their standard spread betsBecause the win rate of pros is so incredibly tight, proper unit sizing is the only thing generating actual long-term profitAvoid the 'Lock of the Century' mentality; never risk 20% of your bankroll on a single game just because you feel extremely confident
Tracking Your Bets and Understanding the Vig
