I do think that this is because the government is trying to intervene bitcoins flow, they want to regulate its value because they are afraid that many people will get rich just because of this and they don't want us to earn freely. Also, many banks are controlled by the government and if people are starting to not use banks how is the government gonna earn from it? This is why the market is crashing and hopefully, it will bounce back in the future when the government will stop intervening its market.
