Twenty One Capital climbed Friday, trading up 6.89%, or 30 cents, to $4.66, as the Tether-backed bitcoin treasury company continued to show signs of stabilization following a turbulent stretch that saw its stock plunge to fresh lows after an abrupt leadership change last month. A Company Built Around Accumulating BitcoinTwenty One Capital, based in Austin, Texas, operates as a bitcoin-native public company designed to give investors exposure to the cryptocurrency through traditional equity markets, rather than requiring them to hold and secure bitcoin directly. That original strategy had called for combining Twenty One Capital with Strike, the bitcoin payments company also founded by Mallers, and Elektron Energy, a bitcoin mining infrastructure firm, into a single publicly traded company spanning bitcoin treasury management, payments and mining operations. Zagury has since laid out a distinct strategic vision for the company, describing an approach modeled loosely on Berkshire Hathaway's operating structure rather than a pure bitcoin treasury model. A Pattern Familiar to Bitcoin Treasury StocksTwenty One's volatility mirrors a broader pattern seen across the small cohort of publicly traded companies that have built their business models primarily around accumulating and holding bitcoin, a group that includes Strategy, American Bitcoin Corp and Strive Inc.
