Re: Drop your predictions for the value of Naira against dollar?
As for you question, why no just specify the time. Example is to ask the question that what would be the price of dollar to bitcoin before the end of this year. You can not ask the question in an indefinite way.
Sorry that I did not make it very specific, I been feel say I dun already lay the example of the duration from my own prediction wey I been give wey be from April to June (second quarter) In maybe the second quarter of the year, I predict one dollar to be almost the equivalent of N2,500 because our government seems to be clueless on what to do.
I go dey more specific and plain next time with the duration.
Before the end of this year, I am expecting at least 1 dollar to be 2000 to naira. But at most, it should not be more than 2500.
Your predictions are valid, but at some point too, I never expected 1 dollar to get more than 1000, Nigeria shock me! Nigeria still fit shock you with that 2500 mark that you have set. 
This is not right because I think this is not the question that you want to ask. It is dollar against naira and not naira against dollar. There are differences between USD/NGN and NGN/USD. You are asking about USD/NGN pair and not the other.
Thanks a lot for this correction, I have edited the post and made the correction.
