Rhino Bitcoin (formerly Phoenix Plus Corp.) is a small, early-stage Bitcoin financial services company operating through its subsidiary, Rhino Digital. The company offers everyday banking-style services built around Bitcoin, targeting individuals, businesses, and organizations in the U.S. The core product is the Rhino App, which lets users buy and sell Bitcoin, hold Bitcoin in custody, send international remittances, fund and withdraw accounts in USD or Bitcoin, and purchase discounted gift cards. Rhino Digital's primary revenue comes from the bid-ask spread it earns on Bitcoin-to-USD exchanges, making revenue directly dependent on client transaction volume and spread size. Custody and settlement fees provide secondary revenue. Rhino Digital runs an asset-light model, relying on third-party partners — Cybrid, Cross River Bank, and Fireblocks — for USD banking and Bitcoin custody infrastructure. The company also holds a Bitcoin treasury on its own balance sheet. Rhino Digital plans to expand its product lineup to include Bitcoin-collateralized loans, retirement accounts, bill payments, and direct deposit, mostly targeted for launch in Q4 2025 and Q1 2026. The company currently operates with one full-time employee and four contractors.
