The latest news is that the US government is look closely at Bitcoin. A number of governments such as Russia and China are also planning to issue their own digital currencies. They clearly see a financial threat from Bitcoin.
What do you think? Can governments kill Bitcoin and replace it with their own digital/crypto currency?
I don't think the government can kill bitcoin because it's decentralized, and as long as someone trusts and USES it, it will never die. If the government issued tokens without the user's approval, it would be worthless.
The main reason cryptocurrency can survive is trust.
