An anonymous reader cites an article on Motherboard: Like the changing of the seasons, a natural stage in the dark web marketplace life cycle has once again manifested. Nucleus market, which primarily sold illegal drugs such as cocaine, methamphetamine, and cannabis, has disappeared: The site is unresponsive, and the market administrators have not made any announcements about planned downtime. This has forced vendors to migrate to other sites and panicked users to figure out where to go next, all amidst a whirlwind of rumours and speculation of where Nucleus -- and its cash -- has gone. 'Nucleus is an awesome market. One of the best. Hope all the admins are ok and nothing serious happened,' someone identifying themselves as a vendor wrote in a comment on the news site Deep Dot Web. At the moment, it's not totally clear why Nucleus' website is unresponsive. It could be an exit scam -- a scam where site administrators stop allowing users to withdraw their funds and then disappear with the stockpile of bitcoins.
