Someone ask this
question on Nigerians local board, the reason why miners are not located or negligibly located in Nigeria as a result of poor electricity supply. In Nigeria, electricity supply is poor in many areas and the only option anyone that want to mine can have is to use solar energy.
Assuming you get yourself like one or two Antminer S19 Pro, powering it with solar, will it be profitable after considering the budget and maintenance?
Those miners and solar panels are not manufactured in Nigeria, they are probably manufactured in China which will make them costly as they will be shipped.
Others are saying it might "probably not be profitable", but in this case I am saying it's not going to be profitable. As a Nigerian weighing the circumstances surrounding self power generation in the country is very expensive even for an owner of a small scale business not to talk of mining equipments that are very expensive to afford in addition to the solar panels too. The country is highly import reliance country which means even when it comes to maintenance every parts would have to be imported.
There are many other unfavourable environmental factors to look at too that I think are only peculiar to we Nigerians alone and I believe that's why almost every Nigerian prefer buying bitcoin and hold instead of going into mining cause the profit is not feasible.
