I dont think that the government will support cryptocurrency over fiat. Every government have their own fiat and have some regulations when it comes to crypto use due to the risk that it can cause the public. Besides the central bank still dont recognize it as a currency.
Currently its look like so, but I am sure that with the passage of time their attitude toward bitcoin will change. They will very soon make bitcoin a legal currency and will very soon allow their people to use bitcoin for shopping and other purposes, because they are going to know and understand the importance of bitcoin.
