You are likely to be mandated to spend some amount of time indoors over the next few weeks. Postal services will still operate but in-person dealers may not.

Do not fall for the many bait and scam posts that will be posted on reddit. To remind people

• Someone you meet through reddit offering to sell drugs is a scammer. Good vendors do not need to find customers through reddit.
• Someone who offers to introduce you to their plug through reddit is a scammer. Good vendors do not need to find customers through reddit.
• Anyone accepting non cryptocurrency payment methods is a scammer. They are looking for low hanging fruit who will not spend the couple of hours required to figure out crypto for the first time. This includes venmo, paypal, gift cards, vbucks, you name it.
• Anyone you meet through reddit is a scammer. Just repeating this one to hammer it home.

DarkNet Markets are widespread and the reviews there meant that vendors are accountable for the products they sell. Escrow makes it impossible for vendors to take money without sending product and frankly it's so lucrative that big vendors don't need or want to. Look for the best review history, not the cheapest price.

Bitcoin used to be anonymous for a long time but it has always been possible to publicly trace transactions between accounts. Now that Anti Money Laundering rules require exchanges to keep photo ID for purchases this makes it possible for bitcoin purchases to be linked to your ID.
All markets accept Monero, a different currency which works in the same way but makes it impossible to link transactions between accounts without the login details for the sender account. Bisq, kraken, poloniex and other exchanges allow trading of Bitcoin for Monero and this makes it easy to break the surveillance chain.

Learning to use DNMs takes a couple of hours and will decrease the risk you are exposed to by allowing you to more effectively vet who you are purchasing from. Use DuckDuckGo to search for guides online (DO NOT ASK IN THIS SUBREDDIT) and have a read. Do not ask individuals to help you through the process, they may be scammers. Look for publicly available guides that have had the chance to be scrutinised. Use https://dark.fail to avoid phishing links to markets. Never follow links to markets that you find on Reddit.
