You can easily get the price on other exchanges. Example are these two exchanges:

Use see the price in USDT, you can see naira price below it. That is how it is on exchanges that has naira which is among the fiat that you can use for your balance estimation on the exchanges.
On Coinmarketcap and Coingecko, you can also change it to naira.
