I've seen a lot of old projects that changed the concept to Defi. To me this isn't great because obviously they are using the hype just to revive their project.
someone is crazy about Hype Defi! It's a red light for you, be careful before you cry get caught up in this FOMO.
People investing in any new DeFi based projects be sure that you already invested on some of the most stable DeFi in the market, there are a lot of new DeFi now if you invested on stable Defi, you know what to look and expect on these new DeFi that are coming up educate yourself if they are real DeFi and with a good team behind.
