$BTC Let's assume you invested 1000 dollars. First, the price of the token dropped by 90%: you lost 900 dollars ← you have 100 dollars left. Then it increased by 90%: 90% of 100 dollars = profit of 90 dollars ← now you have 190 dollars. Have you returned to break even? No, you are still down by 81%. (1000 dollars ← 190 dollars = -81%). A 90% drop requires a 900% gain to break even.

This is a theft of your money with love, security, and credibility in the deal.
