Odaily Planet Daily News: Japanese listed company Metaplanet today announced an additional purchase of 619.7 BTC, making its Bitcoin holdings the twelfth largest among listed companies, only behind medical technology manufacturer Semler Scientific. Metaplanet reported that from October 1 to December 23, its BTC yield was 310%, significantly higher than the 41.7% from July to September. Metaplanet uses BTC yield to 'evaluate the performance of its Bitcoin acquisition strategy, which aims to create value for shareholders.' According to Google Finance data, Metaplanet's stock price rose by 5% after the announcement, but it has still fallen nearly 13% over the past week. However, due to the company's adoption of a Bitcoin strategy, its stock price has increased by over 2,100% this year, reaching a historical high of 4,080 yen (26 USD) on December 17. (Cointelegraph)
