Debit cards generally work better to buy crypto than credit cards.
There are several reasons why your card may fail during a transaction. When using a credit card, the most common causes for failed orders include:
- Using someone else's credit card
- Providing incorrect billing information
- Insufficient balance on your credit card
- Your bank or the card issuer declining the credit card authorization or not allowing you to purchase cryptocurrency. Unfortunately, this is not uncommon. In this situation, the best course of action is to either try a different card or contact your bank to ensure a legitimate transaction.
Additionally, you may be flagged as a suspicious user if your usage patterns are irregular. This can occur when using different cards, utilizing VPNs, or inputting unusual combinations of country, fiat currency, and nationality.
Lastly, it is possible that you have reached the maximum buying limits set by the platform or service you are using.
