If its ASICminer, why dont they solomine? Their project is big enough and they're technical enough to make their own "pool".
Guaranteed PPS at this early date might be too tempting. Get the easy money in a predictable manner.
If its ASIC miner there is no reason for them of not having 10s THs online now. They can test one or 2 units. After that they can power all the rack. Its not like they're assembling 12 units/ day.
Again they're reaching for 10s THs, you would have thought they get their own pool up from start?
