This is new tech as well Chris so there is nothing wrong with asking question. I believe said person to have access to allot of pc's or some cloud mining infastructure. Its just speculation on how powerful the systems are but one could assume that theyre i7's and greater. I remember a few weeks ago the guy added all 500 machines to the pool. So I think roughly that;s what the pool is up against. Like I said before someone really wants those BLE and using allot of resources to get it.
