The only downside of Ethereum right now is the network congestion. It forces us to raise gas fees just to make transactions faster. I understand that most of the ICOs are using the Ethereum (ERC20) smart contract for token distribution, and only a few to other blockchain networks.
We are still in the first month of 2018, so it's still a long way to go. If ICOs are still using Ethereum despite the network congestion, there is a chance that it'll hit $10k over time. Just like Bitcoin, from $1k to above $13k today.
For realistic measures, I predict it'll go $5k by the end of 2K18, but correct me if I'm wrong later.
