Coinbase is set to introduce a new American Express card in the U.S. this fall, featuring hexadecimal data from Bitcoin's genesis block as a tribute to cryptocurrency's origins. Exclusively available to Coinbase One subscribers, the card offers up to 4% Bitcoin cashback, adjustable based on asset holdings. Cardholders can enjoy no foreign transaction fees and have the option to repay balances using either their bank accounts or cryptocurrencies on the platform.
