Live up to your current failed obligations before you brag about future "accomplishments".
Otherwise any thing HF says will seem disingenuous.
The 2TH/s Sierra EVO has been hashing live from the Austin BTC confab for days.
IOW, it's not a "future" accomplishment but rather an empirically proven fact of current reality.
HashFast isn't the only entity saying the 2TH/s Sierra EVO exists. cgminer, Eligius, and hundreds of BTC confab attendees also confirm this new world record for ASIC mining.
OTOH, Cointerra's chip is still being misrepresented as "500GH/s" when it actually only gets about 400GH/s. Even after a two month delay, they couldn't get their machines to run at the promised 2TH/s.
The only company in the world selling mining equipment that really hashes at 2TH/s is HashFast (hence our name).
