Do not invest into DeFi tokens that already experienced bull run, rather find coins that are attempting to the market, like Radix, Dfinance or Oikos token.
Bull market is relative, some have had good run but the whole space will have its time. Those having a good run are built on ethereum blockchain. If Dfinance follow suit on the same blockchain with wings they could have the same run but Oikos is listed on Tron, listed on many exchange but have struggled to enoy the same ride like other Defi. I also want adoption of more decentralized exchanges
