Cryptocurrency cards, also known as crypto debit cards, have gained popularity in recent years as a way for users to spend their cryptocurrency at traditional retailers easily. While they are still relatively new and not yet widely accepted at all merchants, they have seen a significant increase in usage and availability. Several companies, including Visa and Mastercard, have partnered with cryptocurrency companies to offer crypto debit cards, indicating that they see potential in this industry. However, it is worth noting that the popularity of cryptocurrency cards may vary depending on geographical location and individual preferences.
