I've never bought anything on the dark web.  I've never even used or seen what's there.  I'm aware that TOR exists, but that's the extent of my knowledge of such things.  Been down the drug use route before and have no plans for that again, or anything else that's illegal.  Bitcoin makes buying illegal things quicker, but I don't think it makes it any safer for the buyer.  You'd be much better off paying with cold, hard cash.  That's probably not possible on the internet, but you know what I'm saying.  Cash is way more anonymous than bitcoin.  The police would be able to trace you somehow, believe me.  Plus if you got the postal service involved, yeah.
