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

Without strict bankroll management, an inevitable bad streak of unexpected injuries or bad referee calls will wipe out your entire account.

The Concept of the 'Unit'

Using units removes the emotion from the money, turning your bets into cold, calculated mathematical decisions.

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 bets
• Because the win rate of pros is so incredibly tight, proper unit sizing is the only thing generating actual long-term profit
• Avoid 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

To truly manage your bankroll, you must aggressively track every single bet you make in a detailed spreadsheet.

When you bet on a standard point spread, you usually have to risk $110 to win $100 (odds of -110).

Discipline is boring, but in the world of gambling, discipline is the only thing that actually pays the bills.
