Who knows?, but I bet there's going to be another Era in the crypto sphere after this DeFi Era cause every single day new ideas keep coming up, so someone with definitely think of something it's just a matter of time, remember how ICO, IEO, STO passed? that's how DeFi is going to pass too, but for me DeFi makes crypto completely decentralized and free for everyone, I wonder what the next Era projects will be about.
