Some banks and corporations said theyre halting purchases of Bitcoin and other cryptocurrencies on their credit cards. Banning it because they dont want the credit risk associated with the transactions. Some says that allowing purchases of cryptocurrencies can create big headaches for lenders, which can be left on the hook if a borrower bets wrong and cant repay.
Not all banks in the country prohibit bitcoin and cryptocurrency, depending on the country. For example, Japan and South Korea allow it, but there are many reasons for prohibition, mainly because the cryptocurrency is not under the control of the state. If it becomes the mainstream currency, the country Can not control the economy, and secondly, the investment risk of cryptocurrencies is too high, despite the high returns, but the government will not allow people to participate in all these.
