This is what often happens in our crypto market. When a new trend is created, there will be quality projects, but besides, there are many scam projects. Oikos is also a form of Defi but Justin Sun has denied being behind Oikos's project. It was a sign of fraud, like YAM. So be careful, every investment needs a thorough analysis. Knowledge and experience are very important in times now. Good luck investing in your next projects.
