I started with the first poloniex to become a trader. I bought the first crypt money there. I can not list scam coins, so I am very happy. An exchange that does not allow manipulation and has a proper stance. But over time, I started to deal with other stock markets because of lower trading volume and more usefulness of the competition. But polonyex always has a great value ... I will list many important coins in other exchanges over the next time, and many more users will come back if they are good in terms of transaction volume. It will be very nice for users to extract mobile application without forgetting ...
