As for the KnC miner numbers, they totally, utterly had a plan of flooding the market with something that may be a collective 30% saturation. The numbers sold by the preorders were far less than what they expected to sell ...
How do you know it was far less than they expected?
... and the expenses for this project will run into 4 to 6 million USD when we count their engineering work too.
I'm sure they have surpassed 7 million USD by this point. Does anyone have the actual sales numbers yet?
So selling KnC miners at least to a break-even point and NOT ruining the BTC network seems like an impossible task.
So, you are thinking that KnC miners will ruin the BTC network?
There are so many factors to consider: Will KnC be able to deliver by September? Who else will flood the market with ASICs before KnC gets their products delivered? Where will the exchange-to-BTC rate be in September ... what if the exchange rate drops back down to 5 USD per BTC? How will this flood of ASICs affect us little guys who are mining for only pennies a day?
On the other hand, could this be a really good thing for the Bitcoin economy? Will the Bitcoin economy become stronger, more effective, efficient and resilient, with this increased flooding of ASICs on the market?
