Too late. They already did.
Wasted money for just some little pump which is just for them. That is the problem when someone is controlling it. They could really make some moves that will be against you.
Perhaps now they have learned. Next time they wont be a victim and will come out wiser.
The problem is when someone cannot read what is happening, not if someone is controlling it. A smart trader knows the all around of the stuff he is trading. We know that it is a pump, why jump in and Buy? It would be best to sell and buy at dump. But I guess there is always a first time for everyone, now lots of new people will know that when BCH is skyrocketing, someone is manipulating it for their own benefit. So better not to fall to the trap.
