ethereum is only the king of altcoin and will never be able to shift the crypto king to ever. I mean here is bitcoin. their differences differ greatly. although many say 2.0 will drive ethereum prices but that still won't make ethereum number 1
Ethereum still plays a golden rule in a crypto world since most of altcoins are ether based but still she is always a queen and bitcoin is king and they are both vital to each other, eventhough its price is not as high as bitcoin but still it is one of the pillars of bitcoin.
