Haha, why are you researching this issue? It’s difficult for ordinary people, but banks have diamond platinum cards, or unlimited cards. Of course, they are not truly unlimited, and there are no ones that show a limit of 10 million. Credit cards, because this does not comply with relevant policies and regulations, and even using 10 million credit cards is a huge risk for the bank. I currently have credit cards from 17 banks with a total *** limit of more than 1.2 million
