Castle The company disclosed that it has opened its automated financial platform to individual users. New accounts support the automatic conversion of cash dividends issued from STRC preferred stocks under Strategy into Bitcoin at a pre-set ratio by the user. Users can choose to keep all the cash, buy all Bitcoin, or allocate it between the two options as they see fit.

Dividends are paid in cash first.

Castle indicates that this feature will not change the securities terms of STRC itself. Strategy will still distribute dividends in cash as originally planned, and subsequently, Castle will purchase Bitcoin on behalf of the account holders according to the predetermined ratios. Therefore, what users receive is not the Bitcoin dividends paid directly by Strategy, but a secondary conversion after the cash is credited to their accounts.

Once the proportion setting is completed, the system will automatically execute it on each dividend payment date that meets the criteria, unless the user actively modifies the instructions. Castle This can reduce the steps for users to manually transfer funds between banks, securities firms, and cryptocurrency platforms.

STRC The current annualized dividend yield is 12%.

STRC is fully known as Strategy, a variable-rate Series A perpetual preferred stock listed on NASDAQ with a par value of $100. According to the disclosures in Strategy, since the record date of September 2026, the annualized dividend rate of STRC has been 12%.

However, this 12% represents a variable annualized interest rate that is not fixed. Strategy indicates that the dividend yield can be adjusted on a monthly basis, and the actual return will also be affected by the purchase price. Moreover, each cash dividend still requires approval from the board of directors.

Castle also mentioned that STRC is not the same as directly holding Bitcoin. The price of preferred stocks can be higher or lower than the $100 par value, and the issuer's financial condition, market demand, and changes in dividends can all affect the total return. At the same time, Bitcoin purchased after dividend conversion is also subject to its own price fluctuations.

• STRC Dividends are first paid in cash by Strategy.
• Castle Execute Bitcoin purchases again according to the set ratio.
• The payment cycle will continue to follow the current bi-monthly schedule of STRC.

Personal accounts evolved from corporate customers.

Before this launch, Castle mainly served enterprises and non-profit organizations, helping clients automatically manage cash, income-producing assets, and Bitcoin portfolios. The company stated that many existing corporate clients wished to use similar tools for their personal finances, which prompted the introduction of personal accounts.

Castle, co-founder and chief technology officer, and Almeida stated that this feature is aimed at investors who wish to maintain a stable cash income while continuing to accumulate Bitcoin. The co-founder and chief executive officer, Stephen Cole, also mentioned that continuous feedback from business owners contributed to the launch of the personal version.

As of now, Castle has not disclosed the number of corporate clients it has, the expected scale of new individual accounts, nor has it provided information on the minimum account requirements, transaction fees, or the specific exchange rates used when converting dividends into Bitcoin.

Tax and record details have not been disclosed yet.

For American users, this account structure involves both listed preferred stocks and digital assets. Castle does not specify in its statement how the platform will handle related tax records, nor does it disclose whether it will provide users with information on the cost basis of the purchased Bitcoin.

The article mentions that the United States Internal Revenue Service (IRS) currently treats digital assets as property for tax purposes. If users later sell related Bitcoin, they typically need to keep records of the acquisition date, cost, and disposal price, among other details.

Additional information:Castle was founded by Stephen Cole, Jo and Almeida. Investors include Boost VC and Winklevoss Capital. In 2025, the company announced the completion of a $1 million financing round to develop automated Bitcoin treasury tools for small and medium-sized enterprises.
