Ethereum can't take the crown from bitcoin because its clear that BTC has better value than ETH and also BTC has lower max supply too, for ETH to reach 47k seem impossible at this point in time, also why comparing BTC with ETH because they really aren't the same thing
ethereum and bitcoin actually have different fundamental in market , investors look ethereum as smart contract platfrom which provide easinest for developers build their team. although there are huge differences between them in supply but eth and bitcoin still recognized as the king in each part.
I think $4K is still very far compared to the current bitcoin price of $45K, of course etherem can't compete with BTC, let alone take over the popularity of BTC, because BTC is a priority investment by everyone.
only while ethereum solved the network fee ,scalabitlity and supply it could compete with bitcoin in price.
