Checking the various platform ranging from telegram Twitter medium there is no any information related to this exchange. It seems to be an abandoned project that was hyped, but was never made real. I recommend you to keep an eye on the exchange for now and disregard any messages from anyone claiming to be or associated to this platform period as currently it is not functioning and there is no any information about it. But exchanges are very numerous you can choose anyone which will suit you. As a good exchange should be able to provide you with a very nice service and interface to trade, make purchases and sell.
