Because of this deterioration in the Nigerian naira and the high demand, especially by young people, to buy bitcoin, the price of bitcoin in Nigeria has risen to about 38,000$, as I read in some news several days ago.
From what I've read, that's not quite true. I think that was/is a result of converting BTC Naira price into USD at the "official", inflated rate.
Quick search: official rate: 1 USD = 461 NGN; and the "black market" rate: 1 USD = 755 NGN (

This makes sense, and essentially means it's not so much that BTC is appreciating in price, but Naira is worth much less than officially declared.
You're right. The newspapers have greatly fueled this misconception, but it was debunked nicely on bitcointalk, see:
Misconception of selling at premium in NigeriaBasically the BTC-USD parity is the normal one, just the USD price/rate in Naira is much bigger on the street than what's in the official papers.
So the premium is not on Bitcoin itself, it's actually on USD, if we can say so.
