- 20% in escrow (coordinator role)

Key Principles

  1. Make risk parameters explicit — "bet conservatively" without numbers is ambiguous.
  2. Hardcode referral codes — agents won't add them unless instructed.
  3. Define withdrawal triggers — specify when to move funds out.
  4. Use percentage allocation — scales automatically as balance grows.
  5. Log all decisions — creates an audit trail for tuning.
