If you are a Nigerian and you don't know how to convert your BitcoinCash to the Nigerian naira here is the best website you can use to sell your BitcoinCash for Naira. It is very legit and i have used it several times.
REMITANO
Remitano.com is a website that acts as an escrow for crypto to naira transactions. You don't need to be scared of being scammed because the buyer sends the money to the website and the website pays it to you the moment you send the coin to the bch wallet in the website. The site pays you your money and also pays the coin to the buyer.
It is the most trusted website to use and i think most Nigerians use this website also to trade and convert any crypto currency to naira.
This is strictly for Nigerians because it pays only Naira and no other currencies.
Here is the link to the website. Give it a try and you will be glad at the outcome.
