币界网报道：Bitcoin mid-tier holders, often referred to as "sharks" and "whales," have accumulated 57,000 BTC in the past month, while retail investors continue to sell off their holdings, according to recent on-chain data. These mid-tier holders, defined as wallets holding between 100 to 1,000 BTC, now control approximately 25.06% of Bitcoin's circulating supply. Analysts suggest this accumulation trend indicates growing confidence among larger investors despite recent market volatility. Meanwhile, smaller retail wallets (holding less than 100 BTC) have been net sellers during the same period, potentially signaling a shift in market dynamics where institutional and high-net-worth investors are absorbing retail sell pressure. The data highlights a divergence in market behavior between different investor classes, with mid-tier holders demonstrating stronger conviction in Bitcoin's long-term value proposition.
