From the book — Chapter 5. Annualise a monthly return: (1 + monthly)12 − 1. Rule of 72: 72 ÷ yearly % ≈ years to double. Honest broad-market money has doubled in roughly ten years, not months. Long-run averages: broad stock market ~7–10%/year, savings accounts 0–5%/year, government bonds 2–5%/year. A pitch of "1%/month" ≈ 12.7%/year; "3%/month" ≈ 42.6%/year; "12%/month" ≈ 289%/year — no honest strategy has ever sustained that.
Impossible returns, urgency built to stop you checking, and "guaranteed" alongside high numbers are the three Ponzi-pitch tells. Any one is a reason to walk away and, if real money is on the line, consult a qualified adviser. Everything stays in your browser — no sign-up, nothing stored.
