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.
It's a big warning sign to stay away from any project that change their ways for money making sake, it shows that they can do anything without caring about their reputations, it's same thing some projects did when kucoin exchange was hacked, they change their smart contract instantly but these projects claimed they are 100% decentralized.
