If Bitcoin is a peer-to-peer electronic money system, then DeFi is a peer-to-peer electronic financial instrument system. The ecosystem of decentralized finance can provide anyone with access to traditional financial services, eliminating the need for intermediaries and lowering barriers to entry.
How useful do you think it will be in the future and will it be affordable for small investors?
DeFi has huge promise due to it usage of smart contract. it is decentralized, and you dont need intermediary to utilise financial services. Defit will remove inequality from finacial system. You can be an investor wherever you are, regardless of your colour.
The future is promising and is not very good to the traditional financial system. I see disruption coming.
