Hype is just good for those who know when to enter the hype and know when to exit.
Hype is just good for those people who aren't that greedy and when they got some profit from it, they will stop doing it again.

Aside from the 2, I don't think that there is anyone who will benefit from hype. Investors throughout the years are losing their money because of different hypes from the ICO hype 2-3 years ago from the IEO hype and now this DeFi hype. I always say that thing many times before investing into a thing that is being hyped.
