It seems to me that second place is ideal for ethereum. Because it completely corresponds to it, but Bitcoin has always been in the first place.
I agree, many think that because of the ICO Ethereum can become the first, but now that the ico is not very popular, I think it is unlikely that capitalization can overtake bitcoin
No one can overtake or change Bitcoin because he will be the first to arrive anytime because he always occupies the first position.
after the first position, Bitcoin is the second position Ethereum, well he is always next to each other, and he provides mutual benefits for anyone who wants to try to do activities that can produce.
