there are many reasons why the government hates bitcoin, according to my version:
1. the presence of bitcoin can threaten the existence of local currencies, and can damage the financial system.
2. Sometimes, bitcoin used for black market transactions.
3. Bitcoin can be used for money laundering
4. bitcoin is anonymous, so it will be difficult to track.
5. Bitcoin transactions are tax free.
In fact, once these problems are resolved, Bitcoin will receive a green light. The main problem is anonymity! As only Bitcoin owners come out of the shadows, governments will accept Bitcoin as an alternative currency, which in the future will spread along with fiat.
