Metaplanet's head of capital strategy, Shinpei Okuno, has called for Japan to liberalize its capital markets to allow the free trading of preferred shares, particularly those backed by Bitcoin. Okuno highlighted that Japan's current market for listed preferred stocks is limited, with only a few companies like Ito En, SoftBank, and Infronia participating. He emphasized that enabling the trade of preferred stocks such as STRF, STRK, and STRD could attract a broader range of investors by offering financial products with fixed dividends supported by Bitcoin reserves. This move could unlock significant potential for companies adopting Bitcoin reserve strategies.
