That means the statement "The Rock Trading : A good exchange since 2007." is surely some what over exaggerated for marketing and not upto the point. The exchange was basically in operation from 2011 not 2007.
I don't think there was anything crypto related operating before Satoshi Nakamoto's Great idea in 2009.
