How to track your betting & prediction-market bankroll
To track your bankroll, record every stake, result and deposit/withdrawal in one place so you know your real profit and loss — not just a vague sense of how you're doing. The essentials: a running bankroll figure, per-bet records (date, market, stake, odds, result), and a simple ROI calculation. For crypto and on-chain activity, tax software can auto-import the transaction side. Here's a system that takes minutes a week.

Why most bettors don't really know their P&L
Memory is biased toward wins. Without a record, you can't tell a genuine edge from a hot streak, you can't size stakes sensibly, and tax season becomes guesswork. A simple log fixes all three and takes minutes.
What to record per bet
Date, platform/market, stake, odds (or entry price), and result/payout. From those you get profit/loss per bet, total staked, and ROI (profit ÷ total staked). Tag bets by type so you can see which strategies actually make money and which just feel good.
Automate the crypto side
If you fund via crypto or trade on-chain (e.g. Polymarket on Polygon), connect your wallet and exchanges to crypto tax software — it auto-imports deposits, trades and withdrawals and computes gains, covering both your records and tax reporting. Keep your own log of stakes/results on top for the betting view.
FAQ
What's the simplest way to track a betting bankroll?
A spreadsheet with one row per bet (date, market, stake, odds, result) plus a running bankroll total is enough to compute profit and ROI. Automate the crypto-transaction side with tax software so you're also ready at tax time.
What is ROI in betting?
Return on investment = total profit ÷ total amount staked. It's a better measure than raw profit because it accounts for how much you risked to get there. Track it over a meaningful sample, not a handful of bets.
Do I need to track for taxes?
In most jurisdictions betting and crypto gains are reportable, so records matter. Crypto tax software reconstructs on-chain and exchange activity automatically; keep a stake/result log alongside it. WeeBet isn't tax advice.
