selling via localbitcoin could be problematic. One needs to be very careful when selling bitcoin via localbitcoin. There were many instance on localbitcoin ceased coins of seller just because buyer showed in interest in the beginning and backed out at last minute. There are many whatsapps groups as well or telegram groups are there. you could sell coins on other crypto exchanges link coinsecure.

Anyway it is better to purchase coins from the secure and verified entity than unknown entity. It could be a trap.
