A prominent Bitcoin early adopter, referred to as the Bitcoin OG, has been actively selling large amounts of Bitcoin (BTC) to acquire Ethereum (ETH) over the past week. Initially receiving 100,784 BTC seven years ago, valued then at $642 million and now worth approximately $11.4 billion, this whale has deposited around 22,769 BTC worth $2.59 billion to the Hyperliquid exchange for sale. Concurrently, the investor purchased 472,920 ETH spot valued at $2.22 billion and opened a 135,265 ETH long position worth $577 million. Over the subsequent days, the whale closed 130,564 ETH longs at an average price of $4,692, realizing a profit of $42.5 million, then bought an additional 33,381 ETH spot. In total, the whale has acquired 544,977 ETH valued at $2.55 billion and staked it. More recently, the whale sold an additional 1,000 BTC for $109.68 million and opened a 96,452 ETH long with 5x leverage, with a liquidation price of $3,458.8. Within the last 14 hours, the whale sold 3,968 BTC worth $437 million and bought 96,531 ETH spot valued at $443 million, closing the 96,452 ETH long for a $2.6 million profit before flipping into spot purchases. Over the past week, the total ETH accumulation reached 641,508 ETH worth $2.94 billion. The whale has sold approximately 27,000 BTC, equivalent to about $3 billion, and converted these proceeds into Ethereum. The BTC holdings have decreased from the initial 100,784 BTC to about 3,250 BTC remaining, valued at $360.75 million. This activity has drawn attention in the crypto market due to the scale of the rotation from Bitcoin to Ethereum.
