I am sure that the crypto-currency market is manipulated in order to expel inexperienced traders, thereby making money. Do not panic.
The price of bitcoin dropped is normal, so does the price of bitcoin rises. This is a business, where prices rise or fall can be designed by bitcoin bigboss which has a lot of bitcoin and is thrown into the market to make prices fall apart according to their wishes. The goal is simple, he will buy when prices go down and sell them again when prices rise.
