i think ETH does has a small chance to be pumped x10 but don't put too much hope it will happen soon because the market is not fully recover yet and the world need more time to apply ETH or other altcoins in real life more frequent before it can be pumped more than 1000$, i guess we can have double the profit if we start investing in ETH from today.
If ethereum follows their white paper like maximum supply limit also if they implement proposed Casper POS then there will be a huge chance of increasing its time even more than 10x . But when it will happen nobody sure about.
