I have tried it once out of curiosity and I got a little bit scared because I did not know how to use the VPN (I am not sure whether or not the TOR hides your IP address or you should use the VPN when you open it). But either way, I learned many dark stuff and it was quite interesting. However, I did not make any attempt to buy things from the darknet. I just surfed it and read many things just to feed my curiosity. But it was such a good experience.
TOR is more used in the gambling industry because most of the people were from banned countries but still they can gamble by using darknet.Ofcourse no one can trace us there is no identity will be there to trace so if you want to buy some illegal things or explore some illegal contents then you can use it.
