Sushiswap and UNI are more satisfying to me than some DeFi projects because of their use case, they will stay alive for a very long term, this is something we have to consider when choosing projects, another ones I have interest in is ChainLink, Polkadot and Avalanche, it's always about high quality use cases
I agree, usage of the coin does give a great perspective for investment. I also got LINK and DOT but also ADA and IOST. There might be other interesting coins to invest but it is all about finding them... In any case, investing now in the anticipation of the Alts season should be a good move.
