During this first wave of decentralized finance projects and services, users have been more than willing to part with their funds. It is very similar to how decentralized exchanges work, as convenience seems to trump privacy and security in DeFi. Just because some platforms offer a high annual percentage yield does not mean anyone should give up control of their funds.
Considering that DeFi is designed to be built on blockchain technology, there is no reason for go-betweens, intermediaries or fees. Unfortunately, these aspects are all present in a lot of solutions today. Regrettably, users have to pay to deposit funds and withdraw them again afterward. Concepts like these will eventually be the downfall for DeFi unless developers address them soon.
