For me I believe that ethereum might grows just like bitcoin since many users now was in smart contract and It confirmed much faster considering that it also provide a small fees we could expect that the price of ethereum might grow just like what bitcoin investors are enjoying now.
Of course, Ethereum has large user base but the number of Ether in circulation is about 94 million while bitcoin has only 16 million. Because of that there's no chance for Ethereum to grow in value like bitcoin.
