The Swiss government has issued a set of recommendations to deal with the current energy crisis, including a ban on heated swimming pools and saunas (which completely undermines the concept of a sauna).

Is any Western/European country currently discussing a ban on cryptocurrencies, which are the perfect example of energy waste? It would be strange if people were urged to do extreme savings, but the industry that provides such huge energy usage, while providing no value added for the society, was not. However, I haven't heard of any planned measures yet.
