i have use tor to dark market in few month,but most market is inviation only,cant to register.
who can give me any hints to join for a market?i just want to purchase sth ,not selling.
It is quite simple in my opinion to sign up... Just go to deepdotweb.com and see the list of the top markets, pick on the one that you trust the most, type in the .onion url in your tor browser, and it should pop up with a sign up or log in page depending on the website.
Remember also use multisig when purchasing to reduce the risk of the site itself scamming.
