How to Buy Bitcoin & Crypto with Frost Bank
Frost Bank customers can use their Visa debit card to buy Bitcoin and other cryptocurrencies on CEX.IO through Instant Buy, or move funds via ACH bank transfer and trade once the balance is available. The bank does not restrict its Visa debit cards from being used on regulated crypto exchanges, and the Frost App even allows customers to link external crypto accounts for balance monitoring — making it one of the more digitally forward regional banks in Texas.
What is Frost Bank?
Frost Bank — officially part of Cullen/Frost Bankers, Inc. (NYSE: CFR) — was founded in 1868 in San Antonio, Texas, by Thomas Claiborne Frost, a Civil War veteran who opened a mercantile and banking partnership on the city's main square. In February 1899, it was chartered as a national banking association. The Cullen/Frost name came in 1977, when the company merged with Cullen Bankers, Inc. of Houston, with shares subsequently listed on Nasdaq.
Frost Bank is unique among US regional banks in that it operates exclusively in Texas — 200 branches and 1,750 ATMs across the state, which is the largest ATM network in Texas. Total assets stand at approximately $52.7 billion as of Q1 2026. Despite its conservative, community-first culture built over 155+ years, Frost has embraced digital banking: the Frost App allows customers to securely link external cryptocurrency accounts to view their digital asset holdings alongside their bank balances in one place.
