It doesn't matter where in this world someone mines their Bitcoin. A huge plus that people never seem to mention.
there actually is a difference.
for instance
kazahkstan industrial mining has about $0.04/KWH rate of electric(once you include everything needed)
US residential (home hobby mining) is about $0.12/kwh
EU/UK is about $0.24 average
places like japan/germany can be upto $0.39
so each different region has different costs.
its where the 'value' window' kicks in of 0.04-0.39 which converts to different mining costs.
whereby right now kazahkstan for instance is mining cheaply and able to sell at $30k for a profit. where as japan are not able to mine cheaply but see that buying bitcoin at $30k is 2.5x cheaper than wasting money mining. so they will just buy it cheap.
kenya offering to accept bitcoin miners would need to tempt them with cheap electric costs worthy of setting up in the area.
..
its also worth noting the regions average electric prices to get a sentiment of value if you learn how to calculate mining costs because with energy prices rises, many asic farms on electric supply contracts of X month terms, might expire and have to pay new rates, which affect the value window.
also looking at the different rates in different regions helps you understand the 'support lines' and resistance lines of the markets by knowing where most people think its either cheaper to mine or buy when prices pass over these thresholds.
EG if bitcoin passes over a certain level americans flip from being cheap BTC buyers to cheap miners(to sell) so the sentiment flips over in favour of more sellers than buyers at certain support lines
..
in regards to kenya. because they are moving out of the international trade of fossil fuel their energy costs might become less impacted by the world wide rise in energy prices (the more self sustainable they are the cheaper they can offer electric).
