For me oh, I think say Bitcoin na blessing to us, because no single entity get control over Bitcoin.
Making it more resistance to censorship and manipulation.
E dey empower individual to get direct control over their finances without relying on intermediaries.
The control can be of two types: the first is the control over bitcoin price while the second is the control over your own money. Bitcoin do not give the government or central authority the power to have anny if the two control. But according to your post, you are refrigerator to central authority control like the government.
But regarding economy, bitcoin is an asset and its price is controlled by demand and supply. People buying more and the coin is becoming more scarce which makes its price to increase. In short, bitcoin is an appropriative asset and that is how I see it is helping Nigerians, for people to use it to hedge against inflation.
