One thing that banks are afraid of is how difficult it would be to confiscate CC holdings when the credit card holder defaults on payment. It would be much more difficult than re-possessing a house or a car. A crypto wallet's private keys can be put on a memory stick or a piece of paper and easily removed from the country, with little or no trace of its whereabouts. There can be a high value in some crypto wallets, and the credit card debt may never be repaid, leading to a declaration of bankruptcy and a significant loss for the bank. The wallet still contains the crypto currency, and the owner can later access the private keys and use a local CC Exchange in a foreign country to convert and pocket the money. A nefarious scenario indeed. hokkaido inu
