Large Bitcoin whales are significantly impacting the market, shifting substantial amounts into U.S. spot Bitcoin ETFs amid regulatory changes and rising institutional interest. This shift is fueled by recent regulatory adjustments that encourage greater integration of Bitcoin into traditional finance. Blockchain data shows these whales transferring millions in BTC across multiple addresses for security and to facilitate institutional participation. Key players like BlackRock are seeing significant Bitcoin inflows, with over $3 billion already processed through their ETFs. These transactions have triggered increased market volatility as the movements influence asset liquidity and adoption.
