Just like the title says. If I buy a card on the darknet How do I purchase bitcoin with it?

If it was that easy everyone would be doing it.
But seriously it's much harder nowadays to card BTC then it was a couple years ago, and if people had methods for it they would definitely be keeping it to themselves.

There is a couple sites that dont do KYC/or id verify. You just have to stay on top of it cause they are constantly closing or they wont work in us so proxy is crucial. I got a site hitting right now no I.D, no KYC, but you must pay $100 to fund your accoukesnt, then they let you charge any card. First person to tap in on tele get it. Otherwise $150. Tele= @robertbankes

It depends on where you live. Like in EU,USA it is pretty difficult to cash out btc because of the local laws.
If i would be you just search for local sellers and buy btc/monero from them.
Websites like localmonero etc are good for that.
But i would prefer monero in any case above btc because of it's anonymity aspect.
I hope i could help you.
