NOTE: SILK ROAD 2.0 WAS SHUT DOWN AGAIN, PERHAPS ITS BEST TO WAIT UNTIL THEIR IS SOME STABILITY, AND THE LEGALITY OF THE MARKETPLACE CHANGES FOR THE GOOD.
Circle is a super simple and fast website/company available in Canada to exchange Canadian Dollars for bitcoin via most payment methods (bitcoin is completely legal in Canada): https://www.circle.com/en
Here are the instructions, some may be overkill, depending on what one is doing and where: http://silkroaddrugs.org/silkroad-drugs-complete-step-by-step-guide/
You NEED this browser to access the silk road link: https://www.torproject.org/download/download
The recommendation is to run the browser off a USB for more complete anonymity.
The recommendation is to open the browser through a proxy, which most decent proxies cost a subscription fee: http://www.anonymousvpnsoftware.com/
The link for Silk Road is here: silkroad6ownowfk.onion (remember it only works through the tor browser)
New anonymous crypto coins are in the works but seemingly not ready yet.
Follow the advice of the guide for the safest shopping (at one’s own risk).
