DeFi hype is already over. Now people are taking more attention to legit crypto coins which are supported by PayPal.
as like Eth, LTC, BCH, beside to Bitcoin.
I do not think DeFi hype is over . If it would over then we wouldn't see too much hype on crypto like it is now. About PayPal supporting legit coins I am not sure if you have 100% over your wallet through PayPal . I do not think they allow withdrawal of crypto from their platform
