supercomputer (sc) has revealed himself on #mining channel at steemitchat.com (the guy that hacked pow1 and was dominating the mining list a couple of days until the hardfork) He is @nobody on steemitchat and is known now as the gxt-1080-sc-XXXX miner. He confessed he is using a GPU miner and he has one competitor( @djm34 )?. He said that at some point (due competitions) it will be more profitable for one of them to reveal the code for a bounty....
