Dark marketplaces are bad places lol most people there are there for the illegal business so.. alot of undercover agents aswell. I've heard about this new black market called theMarketplace but it's pretty difficult to enter or something, might be worth reading up on if you are interested.
i guess some of the links on the deepweb that is indexed as a blackmarkets are just a trap made by the undercover agents or the FBI . i have tried to surf the darkweb and entered some drugs and weapon markets just to see if there are actually a illegal stuffs that are being sold there .
Seem users are getting interested to such market these days due to the rise of XMR and SDC price.
I would probably invest to these coins just to get into the market, I've read people from the adult industry are also there. wonder what sort of illegal porn stuff are they trading there when we've seen it all from a horse and a girl to tranny and an old lady lol
