I personally do not use any P2P platform myself anymore but I am in a telegram chat that does exactly that. People write what they want, it could be any coin and it could even be any fiat if you want to, usually our national fiat honestly because it is a local thing. So, people write like "I want 5 bnb for 5000 fiat in x town" and others reply to that person if they agree or if not then it is just ignored. They even started a reddit subreddit as well to write there as well sometimes, specially announcements.

It has worked great so far, they even have "level" type of stuff where if you are a person who has done many trades p2p in that chat and you are a person who is known good enough, then you get higher level and you can trade a lot easier and tell people you are trustworthy. We have crypto exchanges so it is not really that common, but that chat is definitely used a lot.
