Its good to see your post my favourite Bounty Manager. What I think about your question is that many project taking advantages of the situation and raising money. It looks like another 2017 will happens and we have already seen a demonstration through YAM. But there are very good project like DIA which you have managed. I also wants to mention some other project like Oikos, Synthetic, Compound,CRV and some other.
Sure, we have good DeFi project, but there is still high risks. For example, yEarn Finance token YFI already worth
19 130$, higher than bitcoin. The coin was issued on July 18, 2020 and started with $35. A month later, on August 18, its price had already reached $12,800, overtaking bitcoin. Today, the token has reached a price peak in the area above $19,000. In a month and a half, YFI rose by 50,000%. A coin that is only a month old is already so incredibly expensive, I could certainly be wrong, but this is the last coin I would invest in, too loud to call it a bubble, but it can't be anything else. Such a young project simply physically can't create such a real value in such a short period of time, this price is conditioned by faith in further growth, not by project development.
