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. 
no the king will always be the king and it cant be replaced by any other alternatives . even if we say that altcoin have a more better projects compared to btc , many people will still stick to btc because it is the original crypto and also btc is the only popular crypto that is already accepted anywhere whether online or offline .
