Why it matters

Thinking in units keeps strategies comparable whatever your currency.

In practice

Units make strategies comparable across currencies: a “1-unit” bet is ₱50 in the Philippines and ₹100 in India. Most bankroll advice uses units of 1–2% of the session bankroll.

Example

With a ₱5,000 bankroll, a 1% unit is ₱50.
