Compounding is maths, not a promise
This assumes you hit 5% every single trading day. Real accounts have red days. Traders who last treat the curve as a best case, keep risk at 1–2% per trade, and withdraw profit regularly instead of compounding forever.
Pro tip
A realistic 3% per trading day still turns $100 into about $191.61 in a month. Small and boring beats big and blown.
