In most of my reviews I wrote, I always emphases on the fact that you should always make deep researches on cryptocurrency exchanges you try embanking because there are very many exchange out there and many of them are all known scam exchanges so do try to make researches before signing up for an exchange.
I know this exchange, Daexs Exchange is a centralized exchange that is established in South America. Daexs Exchange deals mostly with spot trade but right now, I don't think that really matters because Daexs Exchange is more like a dead exchange. I concluded this because about two months ago when I checked about it, they stated that it was temporarily closed and it date, it still reads the same results. So in case you find any link available to it, try to make researches because it might just be a scammer.
