Does the UK still have crypto atms? I read they were being considered "unauthorised" but don't know if they were actually banned or if it was more something the fca put out in writing.
I did an exchange a few years ago for a cash deposit (back before localbitcoins required kyc) and it felt the safest way to do things - the buyer was very communicative throughout too and there was no meeting up or chance they'd used counterfeit funds.

https://coinatmradar.com/country/225/bitcoin-atm-united-kingdom/I checked news related to legality and there are old articles stating that these ATMs are illegal as declared by the regulator. I will suggest you to wait for replies from members here who are from UK. They can explain ground reality in this case.
