Castle Opens Its Bitcoin Savings Stack to Individuals

Miami-based financial technology startup Castle has announced the expansion of its automated bitcoin savings and financial stack to retail individuals, following strong demand from its existing business clientele. Previously restricted to corporate entities such as restaurants, accounting firms, SaaS companies, and non-profits, the platform consolidates treasury management, fixed-income yield, and automated bitcoin accumulation into a unified service. The core of Castle's product offering is supported by STRC, Strategy's perpetual preferred stock, which pays an annual dividend yield of 12% on a semi-monthly distribution schedule. Under the new personal accounts model, users can customize how their dividend earnings are disbursed, choosing to receive payouts in 100% cash, 100% bitcoin, or any split ratio in between. Most users utilize the split model to cover daily living expenses with fiat while allowing the remaining yield to automatically compound directly into bitcoin. This move removes operational friction for retail investors seeking cash flow alongside long-term bitcoin exposure without needing to manually bridge funds across banks, crypto on-ramps, and brokerage services.
