## The Most Important Decision You Make
The size of your starting bankroll sets the foundation for everything else. Get it wrong — too small or funded from money you cannot afford to lose — and no staking strategy in the world can save you.
## The Two Non-Negotiable Rules
**Rule 1: Your bankroll must be money you can afford to lose entirely.**
Not money you need back in six months. Not money earmarked for anything else. Money that could disappear completely without affecting your life.
**Rule 2: Your bankroll must be large enough to survive realistic losing runs.**
Even with a genuine edge, losing runs of 15–25 bets are mathematically normal. Your bankroll must survive them without forcing a change in strategy.
## A Practical Sizing Framework
1. **Determine your intended stake size** — the amount you plan to bet per standard unit.
2. **Set your bankroll at 50–100× that stake.**
Intended stake: £20 per bet → Starting bankroll: £1,000–£2,000.
Intended stake: £50 per bet → Starting bankroll: £2,500–£5,000.
This 50–100× ratio ensures you can survive a 25-unit losing run without dropping below 50% of starting capital — the minimum to continue staking at your intended level.
## The Under-Capitalised Trap
Many bettors start with £200 and try to bet £20 per unit (10× bankroll). One bad week of 10 losses leaves £100 — 50% drawdown. The psychological pressure to "recover" is immense and leads to poor decisions.
Under-capitalisation is the most common reason bettors with genuine ability fail in the short term.
## Starting Small Is Not Failure
A £500 bankroll betting £5–£10 per unit is a legitimate starting operation. The goal in the first 6 months is to build a validated track record, not to maximise profit. Profitability compounds — starting small and building correctly is always superior to starting large and blowing up.
