$4B Whale Flip: Why Ethereum Is Winning Over Bitcoin Right Now

Quick Highlights Whale dumps $4B in Bitcoin, piles into Ethereum fast Massive trades mirror rising Ethereum ETF inflows After 7 years silent, whale resurfaces to shake crypto A Billion-Dollar Whale Resurfaces A major Bitcoin holder, known as a whale, has shaken the crypto market with a bold shift into Ethereum. According to Lookonchain, the whale offloaded billions in Bitcoin and accumulated nearly $4 billion worth of Ethereum — the second-largest cryptocurrency by market capitalization. Lookonchain reports that the whale sold 2,000 BTC (around $215 million) and bought 48,942 ETH in just four hours. The day before, the same whale sold 4,000 BTC and purchased 96,859 ETH. In total, the accumulation now stands at 886,317 ETH worth almost $4 billion . Seven Years Silent — Then a $2.5B Splash Arkham Intelligence revealed that the whale had been dormant for seven years before suddenly re-entering the market. In just one week, the wallet purchased $2.5 billion in Ethereum . At its peak, the whale’s Bitcoin wallet held more than $5 billion. This timing isn’t random. The whale’s activity coincided with a broader shift among exchange-traded funds (ETFs). According to SoSoValue, Bitcoin ETFs recorded $751 million in outflows in August, while Ethereum ETFs saw $3.87 billion in inflows. Market Impact and Timing Analysts warn that such massive moves can ripple across the market. Traders often copy whales’ strategies, amplifying their effect. The timing also overlaps with a major milestone for Bitcoin. On August 14, 2025, Bitcoin hit a record high above $124,000 before correcting by 6.49% by month’s end — ending a four-month rally. With Ethereum gaining momentum in both whale accumulation and ETF inflows, the question arises: Is this the start of a deeper rotation from Bitcoin into Ethereum?
