Roxcoins marketcap is not even 500 BTC. You know I open a sell order of 1 roxcoin valued at 1000 BTC doesn't mean its a 1000 BTC sell wall. There's not alot of sell orders at cex so the weirdest orders are going to show. If someone were to dump alot of rox it would be done on bittrex as the volume is much higher.
