It's not fucking hard. When properly implemented (like on the now deceased EIC) all a buyer had to do was literally copy and paste an address into his or her settings and then send x amount of coins to an address. As long as everything goes smoothly with the transaction you don't have to do jack shit other than finalize on market like you normally would. And even when it doesn't go smoothly, it adds ONE step.
I refuse to believe this is above anyone's skill level who has managed to set up tor, set up a bitcoin wallet, buy bitcoins, set up and use PGP, navigate to an .onion site, and use that site to get illicit substances delivered to your door.
If you're going to post a response like "EIC exit scammed and they were multisig, AB and Nucleus have been around forever and they haven't exit scammed. Therefore multisig must be the devil." Just shut the fuck up right now and refer to this Wikipedia page
If you're going to post a response like "Multisig is an OPSEC nightmare because LE can see that transaction and automatically associate an address with you." Then I have a question for you: Why is your bitcoin address associated with your identity at all? For the love of god TUMBLE YOUR COINS.
If you're going to post a response like "I'm a lazy fuck who can't be bothered to put anymore than the absolute minimum into getting my drugs." Then get the fuck off the DNMs this isn't an easy place to be. If you don't have the motivation to use a basic service to save your coins from being stolen, then you deserve to get robbed.
Like it or not we're all criminals here. I don't know why any of you would trust some random criminals that set up a website and said "I pinky promise not to take your money." I don't know about any of you guys but I'm done with the DNMs until another 2 of 3 multisig market pops up.
multisig is too hard
