It's important to take into account that these calculations were based on several factors such as eight different ways people mine Bitcoin (each with its own hash rate) and a mining difficulty of 53,911,173,001,055.00 as a benchmark (which gets adjusted precisely every 2,016 blocks). Furthermore, while these countries offer low electricity costs for mining 1BTC it doesn't necessarily mean they are reliable or consistent sources of power input for setting up mining farms. This is why many countries have actually banned Bitcoin from being mined or traded within their borders due to concerns over energy consumption and lack of regulation on cryptocurrencies in general.
If you're looking for cheap places to mine one BTC then Lebanon (266.02inUSD), Iran(532.04), and Syria ($1,330.10) might be your best bet but keep in mind that these countries lack reliability and consistency when it comes to power input which means setting up a mining farm there might not be very practical after all!
