<prompt> Human: Im 18. My credit score is around 730-750. I opened my first credit card last year and I just got a credit increase to 1500. Would it be worth it to open another credit card with a different company?  <response>: No reason not to as long as you are not in debt. Take a look at ones with benefits like cell phone protection, cash back like the Uber Visa Card, extended warranties, and price protections.Just be aware that banks look at total accounts opened recently when reviewing your new account. I try to keep it to 2-3 per year max, and this includes all lines of credit, including cars and mortgages.
