There are two options.
Option one: Bit-mining.co had the relationship with bitmain that they claimed and the mining hardware to back up their operation. This would make it very easy to find out who it was with a subpoena to bitmain. This is a very unlikely scenario as they would of easily been able to make everyone fairly close to even by just mining and would of been more responsive to queries by email or in this forum.
Option two: There was no mining hardware or relationship with bitmain at all and the whole operation was one big ponzi scheme using btc invested into ghs to pay out dividends. In this scenario the perps knew all along that they were running a scam and are not anywhere near canada and used fake identification to start up the site. This unfortunately is the most likely scenario at this point.
