To buy BTC without KYC we use a bot, lnp2pbot. Mostro is being established in Nostr. There is a platform called Qvapay where you can buy dollars with Cuban fiat, CUP or MLC, and with that dollar you can buy BTC. It does not use KYC, just link the telegram account. In P2P, the phone number is used to confirm the fiat deposit.
The geolocation measure is given by the use of VPN, Cubans cannot buy in online stores in the United States if we are in Cuba.
