If you want to carry a large balance on a credit card, hat features should you look for?

You cant "carry" a large amount on a credit card, as a credit card is for "borrowing money" and then paying it back at a later date. If you wanted to spend a large amount on a credit card, you would want to get a credit card with a high limit, meaning that you can spend more before you have to pay, as well as a low interest rate or an interest free period, so that you would pay closest to the money you previously spent instead of paying more in the form of interest.

It should be by long pressing on the name of an answer if not i'm on a pretty old phone so it might be different for me
