Zg Top is not a top quality exchange. It is in fact, all the contrary. This network is being considered one of the most dangerous sites of current trading world as it offers a kind of connection that is not private, and there has been evidence of some users who inform that when they click anyway, the network does not appear, but other site containing a suspicious information.
So, based on this, the best suggestion is to keep as far as you can. Do not even consider to list the page in your resources, just forget it and let it go. Zg Top won't help you. It will hack you since it is a scam.
There are not solid and reliable features in this page. Take your precautions.
