Government will not kill people who are using cryptocurrency because some of the government employees are also a hodlers, they can prohibit you from investing but not to the point of killing you. We all know billionaires are slowly adopting the technology so obviously they have the connections to the government. Dont be scared, government will adopt this later on.
Those people in the government or those people who rules the country is also a hodlers and belong the crypto world. They actually not intend to kill those people who are in the crypto world because many of them is in that kind of world also. Many billionaires are adopting the new technology and those billionaires have the connection to the government so I don't think that the government is scary that much.
