Castle has opened its bitcoin savings platform to individuals, extending a product that had previously been reserved for businesses.

The company said the personal-account launch brings its yield product to individual users and adds what it described as a first for the category: the ability to decide what share of dividend income is paid in bitcoin.
That yield comes from STRC, Strategy’s perpetual preferred stock. Castle added the product earlier this year, and it currently pays a 12% annual dividend on a semi-monthly schedule.
Users can choose cash, bitcoin, or a mix of both
In a Tuesday statement, Castle said holders can take 100% of the payout in cash, 100% in bitcoin, or anything in between.
The company said most customers settle somewhere in the middle, using part of the distribution for operating expenses while the remainder is automatically converted into bitcoin every time the dividend is paid.
Co-founder and Chief Technology Officer João Almeida said investors have long had to choose between earning steady yield and holding bitcoin. Castle’s setup is designed to remove that trade-off by automatically converting a portion of dividend income into bitcoin, giving customers both cash flow and bitcoin exposure over time.
One platform for cash management, fixed income, and bitcoin accumulation
Castle said its broader pitch is consolidation. The platform combines operating cash, fixed income, and bitcoin accumulation in one place, replacing the need to move between a bank, an onramp, and a brokerage.
The system is built around automation. Users set a strategy once, and the platform carries it out on their behalf.
Launch followed demand from business customers
Until now, Castle worked only with business entities. The company said its customer base has included restaurants, gyms, churches, accounting firms, e-commerce shops, auto dealers, SaaS companies, real estate businesses, and non-profits.
Castle said the move into personal accounts came directly from those customers. Co-founder and Chief Executive Officer Stephen Cole said the feedback from business owners was repeated often: 「I love this stack — when can I use it personally?」 He said the company is now answering that request, bringing the same automated bitcoin-focused financial stack from corporate balance sheets to personal finances.
