Don't buy illegal things over internet. Sooner or later you may end up at jail.
I agree that it's too dangerous to do illegal things through the Internet, but you can also be easily caught outside
Yes thats true . Its easy to be caught outside than being online because in the online world there are tools that we can use to mask our real identity . We can use proxies or vpns and we can use fake names , fake infos and voila , authorities will now have a hard time to detect you . Not just bitcoin but almost any cryptos can be used for dark markets and other dark uses since cryptos are a bit anonymous compare to other centralized online payments
