On-chain data shows that an ancient Bitcoin whale (OG) has sold nearly 4,000 Bitcoins (worth about $437 million) in the past several hours, converting all of it into Ethereum. As of now, this whale has accumulated over 640,000 ETH in the past week.

This move is incredibly hardcore! A Bitcoin OG who has held assets for many years has made such a decisive move to liquidate BTC for ETH, which itself is a very strong signal. This is no longer just a simple asset allocation adjustment; it is a strategic 'belief transfer.'

This behavior undoubtedly provides the strongest ammunition for the long-standing narrative of 'Flippening' (Ethereum's market cap surpassing Bitcoin). When one of the people who understands Bitcoin's value the best starts voting with their feet, it indicates that, in their view, Ethereum's future growth potential has significantly surpassed that of Bitcoin.

Underlying this may be the institutional preference for ETH staking yields, expectations for RWA tokenization, and a richer application ecosystem. Regardless, this OG's movements are worthy of high attention; every buy and sell could be quietly altering the power landscape of the crypto world.
