Zoomex is a centralized exchange established in 2019 by Kirill korzhenkov. This is an exchange which doesn't have a mobile app. This exchange has no margin trading but has quite some defaults like,an inactive telegram group. Also I discovered that when I make deposits, it is not usually displayed which signifies that my funds are definitely not safe . And one factor to be considered when choosing an exchange is user's fund's safety. Besides it doesn't even have a mobile application for better experience. Well, it can't all be bad. This exchange has a very high exchange or transaction speed. And it supports a lot of popular cryptocurrencies. Though it was free before, it isn't now. I guess nothing good lasts
