No, you shouldnt be worried about how much percentage does bitcoin lost. Government they're always around trying to minimize the use of bitcoin, but they really cant. Fact is, bitcoin today can be manipulated by those big players. New investors normaly panic during the price goes very deep just like today, and sell every coin they have to avoid further loss, and thats how the big players like it.
