Blockchain and Cryptocurrency is going to be like the use of biometric to identify people across the borders of entrances into another country. You can't do away with it in the future. Though crypto adoption is gradually gaining grounds and will soon be mandatory in most sector of the economy.
I think that inspite of the governments are trying to harm the cryptocurrency - they will have no choice in the future except to accept it. but it will not be very fast yet
It would be better if government and cryptocurrency will be a friends. Because it helps to grow a really strong and transparent society.
