I cannot find the coin you mentioned on coinpayment. It seems also that coinpayment welcomes any currency to get supported there, even unpopular or a shitcoin as long as the developer agreed to pay certain fee to cover listing review cost.
It's not actually a coin if you check the website they are selling an exchange script it is not a coin as you think.
The link given above is just a list of reviews we don't know if it's real people rated it or bots.
@OP someone already posted this codono site here on the forum from here
Software for a full CryptoCurrency ExchangeI don't think you can trust this I can't find any details from trusted sources about this site.
Much better to hire some developer to make exchange site for you or check this open source crypto exchange from here
