Castle Opens Bitcoin Savings Stack to Individuals, Dividends Redeemable for Bitcoin at Any Ratio

Bitcoin fintech company Castle has announced the opening of its automated bitcoin financial stack to individual users, introducing a first-of-its-kind feature in the category: users can choose to receive dividend payouts in cash or bitcoin at any ratio. Castle's yield comes from STRC, a perpetual preferred stock issued by Strategy that was added to the platform earlier this year and currently pays a 12% annualized dividend on a semi-monthly schedule. Users can receive 100% of their distributions in cash, convert 100% to bitcoin, or select any ratio in between. According to the company, most users opt for a middle-ground approach—covering daily expenses with cash and automatically reinvesting the remainder into bitcoin at each distribution. Castle co-founder and CTO João Almeida stated that investors have long faced a dilemma between stable yields and holding bitcoin, and Castle resolves this by automatically converting a portion of dividends into bitcoin, giving users both cash flow and long-term upside. Previously, Castle served only business clients such as restaurants, gyms, accounting firms, and e-commerce operators; the opening of individual accounts stems from repeated requests by business owners. Castle was co-founded by Almeida and CEO Stephen Cole and has received investment from Boost VC and Winklevoss Capital.
