If all mining were done with 'green' energy it would make BTC more acceptable, but then you have old coal power stations being used. There are alternatives to proof of work that are more sustainable. All that power being used by Bitcoin could be used for other things.
It's still interesting that a country is doing this. I wonder if they will see an increase in 'dark economy' transactions using crypto to avoid tax and other monitoring.
