Nigeria has been pretty aggressive in bitcoin and cryptocurrency as of late, and I cannot understand why. There are tons of traders in Nigeria right now prompting Binance to open up a market to cater the demand, and the government could easily capitalize on this fact by providing ample regulations to sustain the scene and tax the crypto sale proceedings and related profit just like what other countries did. Most countries look up to Nigeria as one of the countries in Africa that is ripe for an economic boost, however if they keep on shutting down opportunities that come knocking into their front door, they'll just keep getting back from square 1 and the number of poverty-stricken citizens would just grow.
The protest is what I am suspecting in the first place. I am surprised because AFAIK there is around 10% or higher cryptocurrency user in the country, putting regulation as the quote above says is the best way to go for anything involving crypto, I believe that this is a political play because you can easily make profit out of the crypto population in your country by putting regulations and taxes, either bankers are involved in this, or a government official that fears that crypto is giving people power or a government official being lobbied by bankers.
