2020-2021 is the year of DEFI and DEX, you should pay attention to Uniswap, Chainlink, Maker, YFI, THOU, and also YFII,
buy and hold, December may be the start of the altcoin season
It does feel like we're entering another altcoin boom. A lot of the old ICO coins look like they will stay dormant, but I think you're right with DeFi. A lot of these DeFi coins will likely blow up, however, I'm not holding them.
