If you think you are going to actually buy something, please protect yourself and use Tails, tumble coins etc.
One of the major tumblers just went offline. People lost their funds. If Darknet Markets switch over to DRK, it'll eliminate the need for BTC tumblers and make their transactions a little more safer and easier. All Darknet markets should switch away from BTC and make DRK their main currency for use.
This is the time for education on why DRK is better than BTC for privacy. Informational videos on how and why DRK is the preferred currency for privacy should be posted on the darknet subreddit and darknet forums. Every darknet user should be using DRK rather than BTC.
