Japanese investment firm Metaplanet has made headlines with its largest Bitcoin purchase to date, acquiring nearly 620 BTC for just under $60 million. This move significantly boosts its total holdings to 1,762 BTC, valued at approximately $168 million. Dubbed "Asia's MicroStrategy," Metaplanet's strategy has delivered a 310% BTC yield from October to December. The firm plans to expand its Bitcoin strategy into a formal business line, including loans and equity. Despite a recent dip, Metaplanet's stock has surged over 2,100% this year, reflecting its aggressive Bitcoin adoption.
