Miami-based startup Castle is opening its Bitcoin savings product to individual customers, according to Bitcoin Magazine. The offering provides access to a 12% STRC yield through personal accounts. Customers can also choose to direct any portion of their payout into bitcoin, linking the savings product’s returns with BTC accumulation. The move expands Castle’s Bitcoin-focused savings stack beyond its previous availability, although the supplied report does not provide further details on eligibility, account terms, or the product’s launch timeline. Bitcoin Magazine published the report on September 8, 2026, in an article by Mathew Di Salvo.
