China's digital currency hasn't come out yet. Who needs to promote it? Digital credit cards are used to collect people's information, and the other is to cheat people about the "activation fee", which is fake.
Credit cards are issued by a commercial bank. Many credit cards have corporate co-branded cards, no matter what kind, they are issued by specific commercial banks. May I ask the participants: Which bank issued this digital currency credit card? Which company jointly issued this credit card? There is no clear bank! There is no clear legal person joint name, because this is fraud.
