Ukraine: This country Have the lowest electricity cost in Europe. Ukrainians pay $5 cents for a kilowatt hour of energy. Bitcoin mining in Ukraine is perfectly legal and crypto-friendly and they are even building a statue in Satoshi Nakamotos honor replacing a Lenin statue [3]. Do not worry about the war with Russia is all over now. You can bring your machines from nearby countries like Germany and the speed of the internet is not the best but is ok for mining. The price for mining 1 b is $1852
Regarding Ukraine, I can say the following: since yesterday, martial law has been imposed on a large territory of Ukraine for the next 30 days and no one understands exactly what this means. Bitcoin mining is not legalized. There are no laws that would ban it, just as there are no laws that support it.
