The first thing that comes to my mind when it comes to Africa and crypto mining are the temperatures that are actually very high in most of Africa which I guess raises the price of mining due to the extra cooling of the mining devices. But I looked at how Kenya stands on this issue and it seems that the location of the plant is still in a more temperate climate zone so the whole thing makes some sense.
Yeah, speaking from experience too, it's the second coldest African country I've lived in (Ethiopia's frigging cold in winter). Compared to rest of Africa is much cooler in Kenya due to elevated land (for me, relatively anyway, from Southeast Asia, Kenya or at least Nairobi areas, it's really chilly. Right now actually 15 degrees Celcius, which is cooler than most air-conditioned places in SE Asia). Also it seems to be getting weirdly cold there -- 2 years ago massive hailstones destroying crops all around, snow occasionally since mid-2000s. So maybe it's less of an issue there (possibly even slightly more advantageous than in other parts of low-land Africa).
