We have lots of challenges facing the country when it comes to bitcoin mining and i don't think we ever had one mining rig before, because this has more in demands for setting it up and i don't think the country has the best offer to help make this a reality of r those that might be interesting in mining bitcoin, except for the international collaboration, whereby they come to set up one and fully fund it.
Here are some few in-demand challenges in setting up a mining rig in Nigeria.
1. Electricity supply
2. Technical know how
3. Government regulation
4. High resolution computers
5. Ant Miner and other mining set up requirements
6. Geographical location/environmental factors
7. Capital intensiveness, many couldn't afford setting up a mining rig.
these among many others could not make mining in Nigeria more adaptable and affordable by many who may be interested
Generating electrical energy sources has been the best option for the Bitcoin mining ecosystem globally and this is one of the many areas we are getting it wring here in our country. Just like you pointed out, there are few other challenges as to ensure steady and successful Bitcoin mining activities here. But if we narrow our talks down to electricity supply, we can say that the government has a big role to play, just like the OP has said earlier.
As of 2019, just like the link the OP shared in this thread above, that a study by coin shares estimated that at least 74% of crypto currency's global consumption came from renewables, mostly in the form of relatively cheap, Chinese hydropower. This is where the government comes in. Enhancing the level of power supply in the country is a major deal and will in a great way set a move on the feet of lovers of Bitcoin miners in the country. There are other cost involvement to succefully min Bitcoin. This will be way too much as people who think of involving I'm Bitcoin mining may think or may not afford. But if the government comes in, create a reliable plus sustainable electricity supply round the country, it will not only lessen the financial burden on miners, but also encourage other would be Bitcoin miners to come on board as they will Chanel their resources to other areas in ensuring a successful Bitcoin mining process.
If you ask me, the government has a very big role to play in this because if you properly examine few other countries involved in Bitcoin mining, they have helped in creating a level ground in amenities which make such mining activities successful. The Nigerian government may not have made rules against Bitcoin mining in Nigeria, but can help in fast growing it's activities if they put few things in other.
