This service is available to U.S. customers, and Uphold plans to extend trading hours to 24/7, five days a week. When conducting 'crypto-to-stock' trades, Uphold will first convert users' digital assets into U.S. dollars. Fractional trading on Uphold is officially provided by registered broker-dealer Uphold Securities Inc., which is affiliated with FINRA.
