In my opinion we are able to purchase something with bitcoin, becoming legal or ilegal, but those transaction is created into the darkish market segments, you can buy drugs within the roads with bitcoin, at least it might be the first time i hear about such factor. Our medication does make medicines to our physique, soo everybody does use medicines, even being altered to create some impact in our body.
Nope the darkish market currency of choice is not btc and not drk (darkcoin

) now called dash.. the favorite currency for the dark market is monero (XMR)
btc has actually come into the light as there are more wall street folks buying into it.
not sure if you are a bot or real person.
vtc has been 'stalling' their stealth address implementation for reasons not mentioned.
