In Ukraine, the cost of mining after halving is approximately $42,000. For comparison, in the USA it is $107,000, in Germany — almost $270,000, and in Italy — as much as $306,000.
The cheapest mining is in Ethiopia ($2,000), Sudan, and Cuba (less than $4,000). But there is a nuance: not all of these countries have enough hash rate or mining is not allowed everywhere.
