People must engage themselves once they understand the nature of crypto and gain knowledge on what they should know and not because of another hype like defi in crypto world.
Defi is something new but just like ICOs there are scam out there, going with the flow on the new hype to scam others. So dont trust easily and know the facts first before investing because not all defi projects are legit.
if you will use diversification and invest in equal parts in all Defi projects, then even without analysis, 40-50 percent of your investments will bring you huge profits
