Ethereum Has Faced a Real Test

I have a lot of problems with Ethereum. I would never invest money in something where something bad happened to Vitalik Buterin. The Dow hack is an example where they said, we're going to roll back a payment that happened on Ether. That just completely shows that this system is not immutable. If it's not immutable, then just use a database. Blockchains are inherently inefficient. You only use them when you're solving a problem of social scalability. As soon as centralized finance makes reference to something in the real world, decentralization loses its value because states can come in and regulate those things very easily. DeFi is going to fall apart again just like the ICO craze
