Bitcoin traded near the $91,000 level on Monday, Dec. 30, down by 15% from its highest level this year. This decline persisted despite MicroStrategy announced acquiring 2,138 more Bitcoins last week, marking the eighth consecutive week of purchases, bringing its total holdings to 446,400. Tether also added 7,630 Bitcoins, increasing its total holdings to over $7.7 billion. Marathon Digital, Riot Platforms, and Hut 8 Mining, have also continued to increase their Bitcoin reserves. Bitcoin’s retreat can be linked to profit-taking by investors who have benefited from its remarable increase this year.
