At some point for ETH to fully recover, something useful needs to be built on it, there needs to be some progress on the scaling issues, prior ICO's will need to continue to hold the ETH raised and new ICO's will need to raise ETH, that's a lot to have happen.  And, they need to figure out their current inflation rate while making sure to not lose too many miners.  ETH is a really amazing tool and technical innovation, but not sure it's a good investment.
