Two days ago, major banks in the United States and the United Kingdom stated that they would not allow credit cards to buy Bitcoin. In Australia, which has always been mild about cryptocurrencies, some major banks have confirmed that they will not prohibit customers from buying and selling Bitcoin through credit cards.

Australia's major banks have taken completely different measures from Lloyds Banking Group, JPMorgan Chase, Bank of America and Citibank. They currently have no plans to prohibit users from buying and selling Bitcoin through debit and credit cards.

Australia and New Zealand Banking Group (ANZ) said in an interview that they did not prohibit users from buying digital or cryptocurrencies, nor did they accept such currencies as payment methods.

However, an ANZ spokesperson revealed that the bank has been monitoring "abnormal" transactions to prevent potential fraud and fulfill its regulatory responsibilities. In addition, the bank will not cooperate with companies such as "digital or cryptocurrency issuers, traders or exchanges".

ANZ believes that such companies are not regulated and are therefore not covered by ANZ policy services. 

Meanwhile, the National Australia Bank (NAB) said that they may stop cryptocurrency transactions if there are security issues, such as theft of funds from online exchanges. A spokesperson for NAB said: "ASIC advises that given that most are unregulated, users may not be protected or have any legal recourse if such platforms fail or are attacked. We have taken very strict measures to protect customer information and accounts, aiming to reduce risk for customers and protect their funds, and some card transactions may not be processed."

Meanwhile, a spokesperson for Westpac pointed out bluntly: "We currently do not impose any restrictions on credit card purchases of cryptocurrencies."

Commonwealth Bank of Australia has not yet responded to this issue.

However, in the long run, supporting this emerging cryptocurrency industry is profitable. By 2021, the industry is expected to grow at a compound annual rate of 61.5%.
