Be suspicious of any projects that just decide to implement DeFi all of a sudden when DeFi wasn't implemented in the project's features from the beginning, this is nothing but a way to take advantage of DeFi Hypes going on nowadays, if you are a deep crypto fan like myself you should be seeing few old projects that aren't DeFi from birth and start talking about implementing DeFi feature, I'm 100% against this act as it's unclean and dangerous
I'm a recent returnee to the world of crypto, and from what I'm seeing there is a big hype around DeFi.
This is looking like the big era of ICO's from a few years.
I think you are absolutely right! If a project is not thought to be DeFi and out of the sudden changes, there is a big chance that is trying to capitalize on hype and probably is fake/scam.
