Give me your best case against ETH

What is your best case against ETH? I believe in this project and will hold to the very bottom. But I'm curious, there has to be a case against ETH's future success. A wise investor listens to both sides, so why not come to the community that cares about this project the most. You can give me anything; price trajectory, TA, developer feedback, etc. Thanks for always being a (mostly) positive community. I'm glad I found you guys back in 2016.
