Etherium will continue to strengthen with increasing levels of trading volume. The possibility of the release of erc2.0's latest network will also further add to the scarcity level of etherium coins. Investors are also looking at this project and are predicted as the successor to Bitcoin later.
If some are dreaming that Ethereum will be a successor to Bitcoin, then they need to sort their scaling issues, how long will users will be willing to spend more gas fees for every transaction and if that is not sorted, projects will move to other networks and that is what some of the projects are doing right now as they are moving to multiple chains because the investors are tired of spending more fees 
.The way everything turns now, ETH still getting good momentum but there are many alternatives who also offer the same usages, if those new projects succeed we will soon to see ETH to decrease the value. But for now, it's better to sort it up in how you'll be able to earn from ETH as the chance of using this coin for your short ride is very likely possible.
Depends on how you see opportunities and how you address the potentials, hard to predict if which direction you should take, but the important thing is always to find the way that it will favor you in terms of investment.
