A spokeswoman for Rice Bank said the move aims to protect consumers from the huge debt (if the value of the virtual currency plunges) because of the virtual currency purchases.
However, other banks said on Monday Monday that they will continue to allow customers to buy encrypted currency on credit cards.
A spokesman for Barclays Bank said: "As a responsible bank and lender, we constantly review our customer protections and are closely following it." Barclays is the UK's leading credit card issuer Business, its market share of about 27%.
Barclays spokesman said: "At present, British customers can use their Barclays debit card and Barclays card, legal to buy cryptocurrencies."
BBVA, the second-largest bank in Spain, said it has no restrictions on such purchases.
A spokesman for MasterCard International, the world's second-largest credit card international organization, said allowing credit card users to buy cryptocurrencies is a decision made by the issuing bank on credit risk.
A spokesman for Chase & Co. said a credit ban on cryptocurrencies has not yet been processed due to market fluctuations and risks, and Citi spokesman confirmed a similar ban, but no reason was given.
These bans apply only to credit card purchases, and debit card users can still purchase cryptocurrencies.
A Lloyds Bank spokesman said in an e-mail: "Lloyds Bank, Bank of Scotland, Halifax Bank and MBNA Bank do not accept credit card transactions involving the purchase of cryptocurrencies."
