The ethereum is popular and has such a large capitalization, only thanks to the large number of ICOs. Sooner or later, ICO will go to the past and then the ethereum will become less in demand and will fall dramatically in price. For this I believe that he is not a competitor to bitcoin.
ICO runs on the ethereum platform and the number of ICOs currently will make eth bigger and more famous. the price of ETH at this time may still fall because many ICOs are scam and problematic, but in the next few years the ICO will grow older and be selected by itself, at that time the ETH price will to the moon
the second coin is widely experienced increasing development and competition that continues to happen. This becomes an advantage with having both and support for its growth. but when compared to prices, Bitcoin has a much higher price than the Ethereum.
