Odaily News Japanese bitcoin investment firm Metaplanet surged on Monday as it plans to raise about $5.4 billion and add to its $1 billion bitcoin reserves. Metaplanet announced a stock purchase rights plan on Friday that it said was the largest in the history of Japan's capital markets. Metaplanet expects to accumulate 210,000 bitcoins by the end of 2027, several times the 8,888 it currently holds. Metaplanet rose 22% in Tokyo on Monday morning, after a volatile stock market since its pivot to cryptocurrencies in early 2024.
