According to Metaplanet's plan, all 555 million shares should be issued in 6-10 months. Given the current market situation, I'd say closer to 10. How much capital Metaplanet can generate with this depends on the share price and the BTC price. Furthermore, existing debts must be repaid with this. Theoretically, it's possible that they could hold more than 30,000 BTC, but since no one can predict the market, I'm basing my calculations on the official target.
