At the moment, I think investing in DeFi projects on Polkadot is potential and intelligent. Ethereum is congested and transaction costs are too high, it is no longer a good foundation for DeFi projects. The blockchain trend of 2021 is cross-chain transactions, and Polkadot is leading it. Users of DeFi projects on Polkadot will have access to more different blockchains, higher liquidity, and a wider community.
