The past two weeks have been quite a rollercoaster for bitcoin and other cryptocurrencies. In loose chronological order, we have seen:

Rumors that China would halt bitcoin exchange trading

Confirmation that China would halt bitcoin exchange trading

Reports China will proceed with further bitcoin crackdown

JPM CEO Jamie Dimon slamming bitcoin (even as JPM allows its clients to use its platform to transact in what Dimon has publicly called a fraud... for a fee of course)

A hit piece by JPM's head quant 

A hit piece by the Bank of International Settlements 

A hit piece by the Wall Street Journal

In the process Bitcoin went from $4,200 to under $3,000 in just days... and then rocketed back to over $4,000 today as the influence of governments in determining the fate of cryptocurrencies was strongly questioned.
