Everything around the address: getting onto Tor, verifying, paying, escrow, and staying safe.
If you have never used a marketplace like this, work through them in order rather than picking the interesting ones. Set up the browser first, because everything after it assumes the browser is genuine and configured sensibly. Then learn the address check, which is the single habit that prevents the most expensive mistake available here. Then the coin decision, because it is the one choice with permanent consequences.
Access and verification deal with getting in and knowing you are in the right place. Payment covers the three accepted coins, funding an order and what escrow does with the money once it is committed. Safety covers the habits that matter and the fraud shapes that keep recurring. Troubleshooting is for when a page will not load, and it starts by reading the error rather than the symptom.
About an hour for a first sitting if you do it properly, and almost all of that is setup you never repeat. Installing and verifying the browser is fifteen minutes. Hardening it is two clicks. Setting up an account carefully is ten. After that a visit is a couple of minutes plus however long the network feels like taking.
Skipping the download verification, because the file looks fine and the step looks technical. Retyping an onion address instead of copying it. Reusing a username or password from somewhere else, which has nothing to do with Tor and loses more accounts than anything technical. And giving up on a page after fifteen seconds, which produces no information and costs you the connection setup all over again.
That any market is safe. Every marketplace that ever ended was operating normally the day before it did. These guides reduce specific, named ways things go wrong. They do not change what a market is, and anybody promising otherwise is selling something.
