Is there a peer-to-peer marketplace where you can buy and sell in Bitcoin without KYC? Something like Facebook Marketplace but for sats. Does anything like that exist yet?
There is PeachBitcoin app, but you need to check if this is working in your region.
Note that limitations of amounts bitcoin you can trade per month and per year, so it's not the best option if you need to exchange larger amounts quickly.
This is a good option if you want to buy or sell with cash without kyc, but it's not available in all countries yet.
