Very high fees. And most of them hidden. Avoid supercharger, it's a complete rippoff. APY is lower than 1.5% even though they state "Apy 33%, even 61%". I.e. staked 800€ CRO for 45 days and received 1.4€ (edit: it's actually 10 cents) profit. They only care about using peoples money. Answer to developer: no thanks, I don't need to contact anyone, supercharger is a complete scam. You can stake your coin elsewhere for real APY and not these marketing lies!!
