avalon chips and groupbuy hardware comming online from assembly I would believe it were bfl if they had their jalapeno line caught up to current orders and singles caught up to 2013 but they don't and that is where the bulk of their preorder hashrate lies...im just talking out of my ass using opinion at this point....but so are they - until they can give us the qty of units shipped per day (they have no incentive to) we are all simply speculating where its comming from at this point. I remember the avalon site saying that they had been extorted for hashing hardware in Asia maybe that could be it?
Bitfury chips have contributed at least 120TH/s in over the last month. Probably quite a bit more.
