I'm not sure, but in such a market condition, who else does agree that the government used a hidden identity and joined the crypto market to accumulate a large number of bitcoins, then sold it to affect its price? Or can the gov hires a couple well known personality to rule the every day news and kill it slowly?
I do not think that governments will use such methods to discredit the idea of cryptocurrency. Governments have many direct and more effective methods of dealing with cryptocurrency if they want to do this. They can directly prohibit the circulation of cryptocurrencies under various plausible excuses.
