Considering what their claim has been operated for 11 years old, but their trading volume is still untracked [1] and only 7 users are leave their reviews about this site in trustpilot, I don't find any discussion about this exchange.
So I'm pretty sure it's just a new scum exchange that pretend to be an old exchange, old exchange surely will appear on the top 20 if they're still operated until now.
