I checked Coinmarketcap and that exchange site that you mentioned in your post is not even listed there. If you want to trade and wants to trade safely, better trade using those who are already well known, good reputation and has a lot of positive feedback. I say "a lot of positive feedback" because we cant avoid those who lost money in exchange sites to comeback and post something negative to the exchange site thinking that its the sites fault that's why they suffered a loss.
