That is what we were expecting for a long time, that the price will not stay below 4000$ for a long time and very soon the price will again start rising, In fact bitcoin was trading at low price for a long time, but still people were too much confident and that is the reason that they were not ready to sell their bitcoin, i think people are still very bullish and hope that the price will continue increasing for a long time and currency we are not going through any depth but the price will continue increasing.
