Are there any downsides to using a credit card?

If, like a large number of people, you don’t pay off your credit card debt in full each month you’ll have to pay interest on your debt. Interest rates on credit cards can be very high so you run the risk of your debt getting out of control.
Should you decide to use your credit card to withdraw cash you’ll be charged interest as soon as the money is withdrawn and there is usually a fee for withdrawal.
