Let’s talk worst case scenario…

I'm very bullish on Eth. I'm excited for the upcoming 2.0 changes. I read tons of articles/posts/discussions about how great Eth is, how it will solve more and more real world problems, and how high the price can go. I've drank the Kool-Aid and put in a lot of $$$ into Eth. My finger is on the trigger to put in even more. Am I suck in a rose colored echo chamber?

I want to take 2 seconds and do a gut check.

What could go wrong? What is the worst case scenario? What sequence of events would see Eth prices dive? How could Eth 2, POS, sharding, etc go south?

In my mind, I can only see the value of the ethereum platform rise with the upcoming changes. I would love to hear some intelligent/informed opinions arguing that investing in Eth is a bad idea… seeing both sides would help before I invest any more.
