Source text: Nakamoto Holdings, a Bitcoin-focused financial firm, has experienced a dramatic share price drop of over 98% since May, following a $563 million private investment in public equity (PIPE) transaction. The sell-off was triggered when a batch of PIPE shares became tradable in September, causing a significant decline in stock value. Despite the setback, Nakamoto Holdings retains 5,765 BTC, valued at approximately $653 million, positioning it as the 19th largest public Bitcoin holder. CEO David Belic plans to integrate additional businesses, including Bitcoin Magazine and Bitcoin conferences, to enhance cash flow and reinforce Nakamoto's Bitcoin-centric strategy. The company's stock, trading on NASDAQ under the ticker NAKA, is currently valued at around $0.9480, a steep fall from its May peak of $25. In a related development, Metaplanet, a Tokyo-listed Bitcoin financial firm, has announced a ¥75 billion share buyback plan to stabilize its stock price.
