Of course panic sell it is psychological effect, but always is starting from mathemathic/statistic calculations or some extremely bad news for the project.
In my opinion the real price of Bitcoin is much lower than what we see on the market today, and the panic sell for Bitcoin is very real.
sure. Most Bitcoin owners today think about Bitcoin not as a payment tool, but as a way to invest money and get income. For them main and only thing what Bitcoin have to do is growing. Price of Bitcoin must grow. If not - they will sell it. At the moment they start sell it, the price goes down and that activates panic sell. More people sell it - lower goes the price.
