It is very difficult to decide. Ether is in its ATH and that means it might go down.
But on the other hand, There are many reasons that make me believe Either will still go up. I will mention the important ones:
1- Ether is growing every day:
- Governments are establishing their financial systems on Either.
- New cryptocurrencies are based on Either.
- many new ICOs are based on Either.
2- Either has a great team and community.
3- Either is being traded with USD and other fiat currencies directly. It has become independent from Bitcoin in that regard.
