The advantage of a credit card is that when you need money badly, you can get an extra credit card. And then you can scrape together hundreds of thousands of dollars in an instant. The disadvantage of credit cards is that. After one, I want to deal with the second or more. Whenever there is something you like. An overdraft credit card will do. Finally, I fell in love with flowers and flowers. It's like brainwashing people. Spend it. You don't have to pay back the money. You will be dumbfounded when you pay back the money. Because you need to pay back a lot of money and then ask someone to borrow money. Or go to the bank for a loan. After this day, I became poorer and poorer. Monthly income is negative. Turn it over again slowly. Therefore, credit cards must be used sparingly. Don't handle too many cards. Just one or two cards.
