I will like to keep this simple and short, you want to invest in DeFi projects? Yea they are the best presently in terms of fast growth and adoption but watch out for new DeFi projects because they are probably scam, you want DeFi project? Look into those that's been around since 2018 or max 2019, not all newly launched DeFi projects starts development in 2020, DYOR and Play Safe.
I fully endorse your point and even a lot has changed after your post in the defi arena i would still suggest the new people here to only go with established and reputed projects as new projects possess bigger level of risks.
