There are a couple benefits to a credit card as long as you are paying them off and not using them when you don’t actually have the money to pay them off.
It can improve your credit score which is important if you ever plan on buying a house, so you can get a loan.
-There usually aren’t any fees for using the card like most debit cards have (at least where I live).
many credit cards offer a reward system which you can use to get free stuff, or sometimes just cash back. I have a dividends and get a percentage back on every purchase up to a maximum.
So as long as you pay them off monthly, using a CC instead of debit can actually save you money and be a good thing. It’s when you can’t pay them off, and instead just meet the minimum payments that they become a problem since they have crazy interest rates.
