Bitcoin is not for physical transaction but online. If Bureau de change want to deal in bitcoin exchange then they have to create an centralized exchange for people to use their platform. If they are accepting bitcoin in physical in your locations, by individual, and since they are dealing on different currency, I will still not do the exchange because they are government agency and working for the government so they can leak your Banking information to the government.
Anyone who dey deal with them na their own risk. There are many online exchange on ground. Though people go still run am. But instead of creating another one why dem no quick ma use Enaira for the swapping and changing and trading at once.
Apart from even revealing their customers personal information if they decides to create a centralized exchange, any platform they create cannot be authentic like the foreign exchanges we use normally because we know how anything that is initiated by a Nigerian is always not stable because there's gonna be a lot of complaints from people.
People should know that bitcoin is in digital form, it's not in notes as Fiats are so anyone dealing with any transactions about bitcoin should remain anonymous by only performing operations on p2p platforms from trusted and reliable exchanges like BITGET, BYBIT, and some other trusted exchanges.
