If you want to trade unlisted coins, what is the best procedure to do so? Is there any guide for that?
There's not really a guide required for that... Just do this:
1. Is the stranger on Bitcointalk/Discord trusted?
[Yes] -> Go to {2}
[No] -> Go to {3}
2. Ask him how it works and he should be able to guide you through it. For all safety, you could tell him you're recording it and if you say that, you should do it as well.
3. Contact a reliable escrow. (On this forum or something like Bitify)
4. Trade.
If you come across any problems, just specify what you need help on exactly. You can PM me with your problems too, if you want.
