I would advice you to stick to your debit card because honestly, as an 18 year old not earning an income, it may be very difficult to pay for your credit card bills. A debit card is limited to your savings while a credit card has no limits so the danger of that is spending above your financial capacity. However, the BOC F1RST card does give you a 0.5% cash rebate for the total amount billed to you at the end of the month (maximum spending of $500 and no minimum spending) so that would be the catch of getting this credit card. All in all, there is no rush to get a credit card because a debit card can work equally as well.

You can ask your parents for a supplementary card or get a secured credit card.
