How do I buy crypto with a card, and what should I know?

Yayınlanma tarihi 29 Mar 2026•1 dk okuma

In the mb.io app, tap Buy, choose your cryptocurrency, enter the amount, and select Credit Card or Debit Card as your payment method. Add your card details and confirm - your crypto is typically credited to your wallet within minutes.

Fees: mb.io charges a processing fee of approximately 2-4% depending on your payment provider and region. The exact fee is shown before you confirm, with no hidden charges.

If your card is declined, common reasons include:

  1. Insufficient funds
  2. Card not enabled for international transactions - contact your bank to enable this
  3. Bank blocking crypto purchases - call your bank to authorise or use a different card
  4. Incorrect card details (number, expiry, CVV, billing address)
  5. Daily or transaction spending limits - contact your bank to increase if needed
  6. Expired card

If the issue persists after checking the above, try a different card or contact our support team.
