Actually, this Exchange platform was established earlier in the year 2017 and was performing greatly and was really appreciated but it encountered a problem which led to its fall. This exchange I am talking about is Daexs Exchange which is a centralized cryptocurrency exchange which is based in the South American region and was really performing greatly.
However, from the last time I checked, it was closed because it has experienced a crash, it closed due to overload of users so it took much more than it could carry and that affected it. In conclusion, I think I can draw a conclusion that Daexs Exchange fell because of its high efficiency.
