You have added your altcoins on this exchange without getting full details about the exchange and now you are asking about its genuinity I think this you can now tell much better as you have deposit your altcoins and are you able to trade and how is the trade volume. In india if anyone starting exchange is not possible in legal way as it is not allowed. So leaving the older exchanges other all new exchanges are threat as anytime they can shut down when the law crack on them and find them, that time they will run away. So it is much better to use the old exchanges which are more safe.
