The only thing that I don't like about people panic selling is that they usually complain when the price of Bitcoin gets really expensive and they can't purchase Bitcoin cheaply.
It's fine if they are going to sell only if they really need some extra cash for their own purpose but don't ever try to sell all the bitcoin that you had. I really hate panic selling, there's no unity between the users and traders, when this panic selling will be stopped for sure we are going to see the price to fly up to the moon.
