UNI, LINK and YFI are Defi projects that are developing well to date and in 2021 I think the three coins will continue to grow and will provide a lot of profit to holders
It is very risky to predict right now. Because now the bitcoin market is dominating, so the rest of the altcoin is not able to perform better. It is difficult to say now whether there will be DeFi hype in the market till next year. Because every time different hype is created in the market.
Since there is still a lot of time for change in the market, we can hope that the coins you give will give good results to investors.
