As we all know that bitcoin is the king of the crypto universe because it is the first and original cypto currency, and it is undeniably responsible for the invention of blockchain technology, because of the discovery of blockchain technology which is the main reason of the growth of the alternative coins, altcoins are generally defined as bitcoin alternative."
Bitcoin is more suitable for the title The origin of crypto rather than King of crypto because not all alts are going to bow down to bitcoin. Ethereum is one of the example and the centralized coins in the market. Although all alts are the alternative of bitcoin but it doesnt mean that all alts are going to be attached on bitcoin. Anyway i dont understand what is your point on this topic. 
Bitcoin is really the king of cryptocurrency world and even Ethereum bows down to bitcoin. If you noticed that during the price crash of bitcoin the ethereum market also crash down. This is not only happening to Ethereum but to all alternative coins in the crypto market. This is inevitable and the truth about bitcoin. Though in the future we will not know if there will be cryptocurrency that will overcome bitcoin.
