Most traders have noticed that Ether (ETH) price has seriously outperformed Bitcoin (BTC) for months now and the ETH/BTC ratio has rallied more than 230% in 2021 and recently hit a new high at 0.089 BTC on Dec. 9.
To put things in perspective, Ether's $490 billion market capitalization currently represents 54% of Bitcoin's $903 billion. This ratio finished 2020 at a mere 15%, so it is safe to conclude that some 'flippening' has occurred. It might still be far from what Ethereum-maximalists imagined, but it is still quite a respectable run.
