Zipzap and UniDAX was nowhere to be found. I tried to do a lot of research Into this exchange to know more about it's operations but I was limited by the factors that made this exchange appear to have never even existed. I have even seen some people talk about this exchange in a way that refers to it bot providing an exchange trading environment to traders.
Currently inaccessible, the exchange has nothing to offer, you cannot access the platform neither can you trade there. The exchange is pretty much dead. Even CoinMarketCap recognizes the inactive status of the exchange and so therefore matches it as an untracked listing. There is no reason to why one should interact with anything or anyone carrying the UniDAX exchange name. It's most probably a scam attempt
