From observation over the years till date, we have more countries in support of crypto than those they are seriously against it. government may actually take steps to kill it, but I tell you it will not stop crypto. Crypto has come to stay .Even with some the threat, it is still gaining popularity by the day.
I don't think it's to kill cryptocurrency but to prevent the negative impact of cryptocurrency abuse. The government often worries about the abuse of cryptocurrency as funding terrorists, black markets, drug trafficking, etc. On the other hand, cryptocurrency as a form of technological progress provides many advantages in investing.
