That is right. When Bitcoin prices looses significant amount, two types of topics-posts appear on the forum. 1 - "this is the end, bitcoin is a bubble, we have lost everything, sell and etc". 2 - "stop panic sale, stay strong, hold and etc". Instead of being worrier about such price changes, I suggest to open price graph of any top cryptocurrency person have and to observer, that every drop is followed by a growth. Of course, every growth then is followed by a drop, but the tricks is to wait  and earn on price difference. Why sell lower than bought? This is so simple, yet so difficult to understand and believe in.
