Its clearly an indication that the government do not want any asset that they cannot be controlled. And if bitcoin will never be centralized, then they will never come to control it and monitor all its transactions. If they can't benefit it, then they should put an end to it and banning could only be their best option.
When power dynamics are threatened, leaders frequently dread. This goes beyond not understanding bitcoin to not wanting to. Bitcoin's power and decentralization threaten fiat currencies' dominance. Their objectives are so obvious when you delve deep. They prefer throwing away the whole pie if they cant take a slice. Its classic fear of the unknown and control obsession
When citizen decides to take their own fate by their hands I don't know why the elites are afraid. Bit coin gives the opportunity to the citizen to determine the trajectory of his/her own finance without super interference. Well I think people always try to keep others in check so that they may not rise to a height that they assumes too many power. Mind you Finance is power.
