I think Defi hype isn't over yet, people are still interested to join Defi project because it offers something new. Defi tokens also look like having more volatility in prices, it makes the prices of Defi tokens (like LEND, UNI, YFI) easy to rise up or decline. This is probably one of the causes why people are still interested in Defi tokens. They know more volatility means a chance to gain bigger profits although it also means higher risks.
