I hate everything the Rothschild family represent but they do know how to make money. As Rothschild once said - "Buy when there is blood in the Streets". The weak will sell and the strong will buy when the markets are down.
China FUD - Remember China has said many times they will shut down Bitcoin...they can't stop it and they won't. Too many people in China, including politicians, are invested in Cryptocurrencies. The government officials are probably buying more Bitcoin. The state is like the mafia, they want their cut. The government will pass regulations but they will never kill an industry that will bring in taxes to the state.
