Ok it was DJ Miner / whatsminer.net.
By the way, if 30 Th/s would be the goal for a home miner with the M30 series ASIC chips, it would need about 166 of them.
166 * 17 = a whopping 2822 US Dollars.
If one could get a better deal, maybe half a price, then it would mean about 1411 US Dollars. For ASIC chips only.
Ref. M30S/88T has 444 of those ASIC chips.
Well it does say M30, M31 and M32.
I'm not trying to get someone to make a 30TH/s miner for $300.
That was his statement saying that using current chips would cost 3 times as much - but that 3 times as much price he says, is about half the price of a current miner, so
should be about half the performance of a current miner, otherwise if it's about a 5th to a 10th of the performance, it would be crap and overpriced.
He's here - listing this in the Mining section of the forum - listing a poor Hash/Joule performance miner due to using old chips.
Thus, being in the mining hardware section, and not the 'sell computers' section, comparing it to other miners, it's crap.
