Government supporting Cryptocurrency over it's national currency is not that possible .
But assuming it happens, I believe it would go a long way in accelerating mainstream adoption of the blockchain technology.
The governments won't support crypto currency over their national currency we both know that but the point here is just for them to support crypto so that most people who are scared to used Bitcoin will join the race. But we have the governments support Bitcoin as the topic says then we'll have no inflation, people will be financial ok and the price of market will be so high.
This is not true. Government are still studying cryptocurrency and they might adopt it as soon as possible. Cryptocurrency's Blockchain has many uses and benefits to the government such as transparent voting. On the other hand we can't deny the fact that government are still somehow not favor of it as they can't fully regulate it yet as of now.
