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
Adding Defi into their product or platform for a new project can be seen with two perspectives.
If we look positively, it is good that project has realized the current trend and they also want to implement to stay uptodate with the market and so that their product does not look out dated.
While if we look negatively, they added defi to get attention, raise more funds and potentially exit scam.
Both are the possibilities but it is your job to analyse the team and make a decision if they are legit or not.
