Someone just dumped 2000 mnx, what a mistake ..., just before getting listed on a new exchange

How do you know if it is getting listed on a new exchange? I have not read any news that a new exchange for minexcoin? If so, is there a link to where I could find this information? A new exchange would be great to continue for the price to go up.
Sorry for my misleading message. I dont know when exactly they will get listed on a new exchange but given that they are working on it for some time already, there is high probability that soon it will happen.
