Dem dey buy below di normal current dollar price. Why dem go display a rate and dey buy or sell with different rate wey dem no display there?
I Don see am say you never really understand how p2p trading works, first, I will like you to take a look at the image you shared above (this one I my quote), you can clearly see that there is a price there with which your $100 was calculated and potential conversion amount to be received was displayed..
The first screenshot you posted is not really the actual price of the naira to the dollar, what is displayed there is simply another trader's buy or sell order, if you like this price and want to trade with that person, then you can simply click that his trade as and open a trade with him or her so long as the money you are trading with is up to their minimum trade amount.
But if the money you are trading with isn't up to that trader's minimum trade amount, you will have no choice but to look for another trader whose minimum trade amount falls within the amount of money you want or wish to trade, and the disadvantage here is that the buying or selling price of this current trader will or may likely be Lower.
