My question would be; do you ever intend to pay off the credit card? A credit card is unsecured debt. The credit card company can't send a repo man after you for the silver you bought on it any more than they can send a repo man for the steak dinner you bought a few nights ago. They can ruin your credit score, harass you with collectors and even call your family to see if they're dumb enough to pay on your debt but at the end of the day there isn't much they can do. So if you are done buying houses and cars and don't care about your credit score max out those credit cards and get ready to change your phone number. When/if I hit 70 I know my game plan

BTW I'm not actually advising this. It is ethically wrong.
