Well before deciding to sign up to an exchange or not it is in your best interest to make an in-depth study about the company the service they offer and go as far as much as to make enquiries in their various community online be it telegram medium on their Twitter account about its credibility and services. There, you will get overall idea of what you're about to opt into. So always where what your have heard and your needs to see if it will suit you. Qmall attracted me when I look at it among the list of exchanges available. I decided to check its credibility and the times of IT services what I have from all my research is is that I noticed the website is not even going through at the moment and none of it social media handles and channels are active. It is in your best interest to hold on for an official launch of this platform and disregard any website or app claiming to be qmall. Search for other options as there are a lot of exchanges available for you to choose from search for one which suits your needs
