Do we know what the reason behind this massive overnight pump is? According to the data COSS was once trading at .0015 ETH that's a pretty good price jump.
I saw on trollbox HitBtc few people who yell "buy coss" and the best nick one from them are "The COSSINATOR"
It was pump because many time coss exchange not working so some people make pump on HitBtc because there on coss was 5 btc daily volumen and ether nethwork many hours delay and nobody can fast send there tokens to sell when they pump it. So it was easy because asks was very small on HitBtc almost not exist. Plus some bigger buys when coss exchange works and they make easy pump. But already price go down again.
