while they are not doing any real mining there
there are old age cloud mining site that are still up and kicking , with that said , you think they are scam ? no way because if its scam then many complaints were recieve thru the years and the site could be down now but they dont . they are legit because they offer real mining with real returns ( realistic returns ) not too exage . but with this cloud mining we found here, 53 percent is indeed too much and looks so shady anymore .
