He explicitly said he uses ASICs. And the hashrate of a botnet would not be that stable over 24 hour cycles.
"no PC" + a couple of pics from the demo release = explicitly saying he uses ASICs?
Those ASIC's are not available yet, even in China. So unless he works for Gridseed, he ain't using ASIC's (IMO)
Not available for public sale, yes. They just mine for themselves at the moment, no point in selling hardware with the current profatibility.
