Bitcoin seems for like the ancestor which has involved into Litecoin, Peercoin and Ethereum. Bitcoin is definitely the trading king. But Ethereum is the utility and token king. Bitcoin is just the orgin if cryptos.
It would be more like a grandfather and grandson thing instead of bitcoin being the king and ethereum is queen. I agree with ethereum being the utility and token king since it is much easier to used and been a choice by most exchange platforms compared to bitcoin who's value is very high.
