Governments tax absolutely everything and almost every action except breathing (coming soon), but you are right, it is disgusting they are taxing something that hate and don't understand that was created to counter gov's and central banks horrible and failing policies of tapeworm economics.

I would like to suggest that if they are so keen on taxing crypto-assets then let us pay our taxes in crypto, by taxing it they are legitimising it and we should then be able to see on the Blockchain just where our tax-cryptos are going? I wonder if they would mind that?
