They promised to ship in October, and in a matter of days took in over a million dollars, That, on the one hand, wass exciting because bitcoin is progressing technologically, but on the other hand, we were aware of the potential risks. We can’t have a monopoly in mining. It's not very good for decentralization.
So this is when we decided we had to step up and this is when developing an ASIC suddenly became a real discussion. In September 2012, we announced that we would offer 300 units if we could get the crowdfunding to do it. We announced this fully knowing that our competitor would deliver the next month, but that was fine since we simply wanted to get the chips and the technology out there in the wild.
We never intended for this to be a real business. But then lo and behold, Butterfly Labs announced that they were delayed. October came and went, November came and went, December came and went and they still hadn’t shipped. Meanwhile, we’re chugging along.
Then in late January we tried to deliver. Well, we tried. It was almost Chinese New Year and nothing happens during Chinese New Year. Fast forward to now, we’re done shipping the first few hundred units, so we’re 90 percent done with batch one.
