Key Bitcoin wallets holding between 100 and 1,000 BTC have accumulated 65,000 BTC in the past week, signaling strong long-term confidence among these investors. This trend, identified by XWIN Research Japan, highlights the activity of 'sharks' or 'whales' who are moving Bitcoin from exchanges to secure wallets, reducing the circulating supply on exchanges. The 30-day Bitcoin Long-Term Holder Net Position Change metric indicates that these investors are actively acquiring assets, which could lead to upward price pressure if demand remains steady. Despite challenges such as market volatility and regulatory changes, these holders view market dips as opportunities for further accumulation, emphasizing the importance of a long-term investment strategy in the cryptocurrency market.
