To the question of the trend 2021 I would add what new can be in the crypt ? Almost all old big projects like Polkadot, Filecoin have already released their coins. The Graph and DFINITY are next in line. Soon digital currencies will appear and maybe a mass adoption lies in them, but nobody needs the rest?
I think all popular Defi projects in 2021 will show To the moon again. Defi market has just begun to show its full potential and in 2021 investors will begin to understand all the perspectives of this trend
