i think that is not.
i know now Ethereum is a most popular coin but Bitcoin also be the fisrt of cryptocurrency and no can replace Bitcoin.
yes in this time Ethereum in a glory but, how 5-10 years letter.
what Ethereum will same like this

i don't think like that.
I still believe that ETH is better than BTC in some respects and although both coins are great and profitable, ETH is more flexible and compatible with other projects.
