This guy thinks so...
Nick Tomaino, founder of 1confirmation, said he is sure that ETH will eventually surpass BTC in value. He said that even though BTC has a well-established narrative as "digital gold" that institutions have embraced, he actually believes Ethereum has made the most impact as a blockchain over the past five years. He claims Ethereum remains largely misunderstood by many, and describes Ethereum as the blockchain where the world's most talented developers are building the decentralized internet.
May be a tough task beating 60k from below 5k though.
Ethereum is and always will be a good Bitcoin alternative but I do not see a reason why it would become more valuable. In fact, ever since eth became pos, I would say it has become a worse alternative to Bitcoin than it used to be.
So no, Ethereum won't flip Bitcoin.
