I mostly use localbitcons in order to sell my all bitcoins. I am using this site since a year and its safe, fast, and secure. You can find your buyer in just one click and you can see the trusted stats. All you have to do just give them your bank details, Like name, Addressee, Bank name,Etc, and they transfer your money via bank account after sending them bitcoins. When i was not aware about this site, I sell my bitcoin to a stranger and he just scammed my all bitcoin and block me. So better to use this site if you don't want to lose your money.
You should also take a look at
https://bisq.network. It's a good p2p exchange (DEX) for fiat/crypto and crypto/crypto trades. It's working on top of Tor for anonymisation (no KYC!) and uses multisig wallets for escrow. It's still missing volume but it's promising.
