Naira free fall plunges 480dollar

I think there may be a mistake here!

The Nigerian Naira (NGN) is the official currency of Nigeria, and it is not possible for it to "plunge" in value against the US Dollar (USD) by 480 dollars. The exchange rate between the Naira and the Dollar is determined by market forces, including supply and demand, and is typically expressed as a decimal value (e.g. 1 USD = 360 NGN).

If the Naira were to experience a significant devaluation against the Dollar, it would likely be reported as a percentage change in the exchange rate, not a fixed amount like 480 dollars.

Could you please clarify what you mean by "naira free fall plunges 480 dollar"? I'd be happy to help you understand the situation better!
