Honestly, I’d be super cautious about that—it sounds pretty shady. Bitcoin is Bitcoin; there’s no special "darknet version" that’s cheaper unless it’s stolen or part of a scam, and dealing with that could land you in serious trouble. I’ve heard of people trying to get discounted BTC, but it usually comes with risks like flagged transactions that could make it impossible to use on legit exchanges. If you’re into crypto, I’d stick with buying through reputable exchanges and store it in a cold wallet to keep it safe. Anything else feels like a gamble not worth taking.
