The market rates are fall and go up frequently that's something not be worried about that much I guess and also the thing that the market is manipulated to often by big whales to lower the price of cryptocurrency.
manipulated by who? one person or company?
that can make people worry when big whales often manipulating price on all market. because crypto currency become alot of new user to star trading and investment often and they are not enough knowledge about how to time sell and buy.
