it depends how you are measuring it. Of course in terms of Naira everything goes up. Also in dollars. Try looking at it from the other perspective.
Imagine that bitcoin hasn’t gone up. What’s happened? Dollars and naira have lost a lot of value and stock market and housing has lost a little value.
So imagine you save one of your children’s education costs in bitcoin for four years. The amount of work you are required to do to pay for their education will be half or even 1/4.
Of course there are still other risks like loosing your keys, but the point isn’t that it’s a good idea. The point is that it is a new standard whether or not governments and media recognize it as one.
