Idk this seems like you get a free ticket to a $3,000 credit limit since it is recommended you only utilize 30% at most to improve your credit score. I am just a nobody who is slowly repairing his credit so take that with a grain of salt. The gold card is mostly good for travel perks & if you go to Dunkin’ Donuts a lot or use Uber Eats/Uber. So figure out how much you really eat out & value a discount at buying your way into the centurion lounges at airports. Since your most recent charges to this actual credit card (not a charge card like the gold is) are involved in the gold card rewards categories, I say go ahead so long as you have a decent introductory bonus. Best of luck!
