Know Your Edge

First, recognize the razor‑thin margin that separates a winning prop bet from a losing one. Ignoring variance is suicide. The deal: calculate expected value on each wager, then filter out anything that doesn’t tip the scale in your favor. If you can’t quantify the edge, you’re just gambling with other gamblers’ money, not yours.

Define a Unit Size

Pick a percentage of your total bankroll—usually 1‑2%—and treat that as one unit. When a game spikes, that unit might feel like a drop of water or a tidal wave; the point is consistency. A $10,000 bankroll translates to $100‑$200 units. Never, ever, exceed three units on a single prop, no matter how “sure” it looks.

Implement a Staking Plan

Flat staking is king: each bet equals one unit, regardless of confidence level. Some advanced bettors tweak the plan, scaling to two or three units only after a winning streak, but the baseline remains flat. This protects you from the dreaded “big‑loss spiral” that wipes out weeks of profit in seconds.

Track Every Move

Log every prop, stake, odds, and outcome in a spreadsheet or a dedicated app. Patterns emerge when you stare at raw data; you’ll spot which player props you dominate and which you consistently misjudge. The moment you stop tracking is the moment you start guessing.

Adjust for Variance

Bankroll swings are inevitable. When you hit a cold streak, resist the urge to chase. Instead, shrink your unit size temporarily—maybe half—until the dice even out. Conversely, after a hot run, consider a modest increase, but never exceed the original maximum.

Stay Disciplined

Here’s the bottom line: the only thing separating pros from amateurs is discipline. Stick to the plan, honor your unit limits, and review your ledger weekly.
