This is just pure bullshit. Just because Ethereum got a little increase today, you are now confident this is the new king. But common... Bitcoin has so many reason to remain number one that it would be too long to detail it here. Even when ZCash price was higher than 1BTC, we did not say tha it was the new king, so price means nothing to elect the chief of the crypto-currencies. Ether is not a proper crypto-currency, it is rather the fuel of a decentralised computer, and this is the major difference with Bitcoin.
Zcash was never close to the marketcap of btc, the price of a single unit is irrelevant if the supply is much lower.
Ether is not the fuel of a decentralised computer, it is the reserve currency of all new developments in the crypto world. Where once btc dominated the donations towards ICOs now it is ether that overwhelmingly dominates.
You also did not list one of the so called reasons why bitcoin has to remain number 1. In fact Ethereum is more decentralised mining wise than bitcoin, it is more programmable and it is more adaptable to changes.
