Bitcoin has been in existence before ethereum and it has gained enough trust and popularity among users to the extent that it is the most invested in coin in the crypto world. Ethereum too has gain a lot of popularity recently due to its possession of smart base contract functionality used by many ICOs. So both coins has a great tenancy , just that bitcoin is the best between the two. When considering their price, you will see that bitcoin is of the highest price while ethereum price is cheap. So high price increasing rate of bitcoin every year has make it a darling Among investors to the extent that majority of investors considers bitcoin first when they want to invest in crypto currency. So bitcoin is the best of the two.
Bitcoin is not the KING of cryptocurrencies, Bitcoin is the Legendary and ancestors of this currency.
Ethereum, ethereum will never be a queen as long as there are so many potential tokens that are going on her way.
Waves is a cool one and a big threat to it, and how about bitcoin cash? Litecoin and as of now, NEO is getting great.
Many ICO is now getting their token with NEO wallet. that is what Ethereum need to surpass now.
I agree that no coin comes close to BTC, but ETH is the second crypto only to BTC, which kind of makes it "the queen", meaning that its performance is as good and regardless of the competition, ETH has been strong, although following the trends of "the king".
