What type of maths is this? Please stop misleading your audience. Thank you.

This coin $Jager is a retail investor's trap, with no big players involved. A 10% fee is charged upon entry, with a slippage of 7% and a price difference of 3%. If you invest one million dollars, you will initially lose 20%, which is 200,000 dollars. In the long term, it could still drop five times; holding it casually for two or three months has a 50% chance of loss.
