its a random pump which can happen to any coin so far its the target coin by the whale team. what this mean is that some private trading group do deliberately pump and dump coin. if you are lucky you may buy some of the coin and wait till you get 10 to 20 % profit and trade it off again before the price started falling again but remember it is risky because you may also loss your coin in case you buy when the whale are already dumping the coin. if you are familiar with trading you will understand that this happens almost everyday.
I have mined these coin before. I wonder how much it will go? I have few of this coins left.
