I originally bought a stack of ETH that was equal in value to my BTC. My BTC is now roughly twice as valuable as my ETH but I see no reason why ETH couldn't run as high as it did the last time around, relatively speaking. Institutions are fully capable of investing in ETH through Grayscale as well. Ethereum may not have time to fully transition to PoS until the market tops out, though. We'll see about how that affects the price action.
