Market research firm Santiment reports that since January 10, large Bitcoin holders, known as "whales" and "sharks," have accumulated 32,693 BTC, marking a 0.24% increase in their holdings. In contrast, smaller "shrimp" addresses have sold 149 BTC, decreasing their holdings by 0.30%. This trend suggests that institutional investors are buying while retail investors are selling, a pattern often seen at the onset of a bull market. The continuation of this trend depends on retail investors' skepticism towards the current market rally.
