Pump and dump is always there on the line but there are also so many factors that affect the price, maybe pump and dump is really hard today because the volume of the investors is really unstable so then I believe that the value and the price of the coin is also unstable. And maybe due to the huge dip the pump and dump status has moves in a very slow way.
It is really quite difficult to see an intense pump and dump during these days as the value of bitcoin is really unstable. Bitcoin price has been in a dip since the beginning of these year and we could probably tell that the price has not recovered knowing its performance from last year especially at the end of 2017. But knowing that bitcoin is surviving is a sign that bitcoin will still emerge and continue to be the king of all crypto and will reach the highest pump which everyone is awaiting from its lowest dump.
