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!
The latest news about Syria speaks of military operations in the territory of this country, and other countries do not look like a good place for mining due to bans and military conflicts. Iran also has a military conflict with Israel. Therefore, in practice, large mining companies will not build data centers there.
