Will ethereum rise to over $1500 over year end

Yes - if everything goes smooth, ethereum can hit $1500 much sooner. Some analysts expect it to exceed bitcoin by 2018.

Here are the main reasons why ethereum is going up and has a great potential:

More huge companies invest in Ethereum as a potential system to conduct digital currency transactions:
An alliance of some of the world's most advanced financial and tech companies including JPMorgan Chase, Microsoft, Intel and more than two dozen other companies teamed up to develop standards and technology to make it easier for enterprises to use blockchain code Ethereum - not bitcoin - in the latest push by large firms to move toward the holy grail of a post-central bank world in which every transaction is duly tracked: a distributed ledger systems.

Ethereum allows so called smart contracts:
Ethereum is much more than just a system for tracking currency. It also allows people to write what are known as smart contracts into the Ethereum blockchain. Two companies could, for instance, create a contract that would automatically send money to one of them if a particular news authority reported that the Chicago Cubs won the World Series or that “La La Land” won the Oscar for best picture. (As the last example shows, what would happen if the authority was wrong is a more difficult question.)

Because of its capacity for smart contracts — and other complicated computing capacities — Ethereum is viewed as more agile and adaptable than Bitcoin.
