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.
I agree with you, it is very difficult Ethereum to compete with Bitcoin.pasti take a long time to compete with bitcoin. Let's wait for this Ethereum development, whether it can compete with bitcoin in the future.
