...News like central banks decisions and financial crashes do not seem to hit crypto until after a while.
After the decision of the Chinese government to ban mining and cryptocurrency was made public, the market immediately reacted to it by lowering the price. This suggests that any news, positive or negative, affects the price of the cryptocurrency and you can expect a pump or dump accordingly.
No, the market does not work that way my friend:) If more people sell than buy,,, this is when the market goes down, and the opposite is true.
China ban moved the industry OUT, that is all. Once the miners set up elsewhere, and the Chinese government realizes all the income they have lost from possible tax revenue and electricity charges, then they might change their mind.
