Well considering the BE300 numbers are real.

Is a cost of $0.23 per GH for the Miner

Lets compare to SP20 at UnderClock or S5 miners that exist for some months.

SP20 list price for 50 units including shipping is $366 lets say $30 is shipping cost list price with no discounts shipping not included is $336 an SP20 at 1.2 TH uses 0.49W per GH and the cos is $0.28 per GH without any volume discount for a large order.

Production time 3 Month.

A conservative difficulty estimation for 3 months is 15%

$0.23 x 1.15  = $0.26 today.

Also even if we can be optimistic there is a risk involved in the investment in a chip that does is not widely tested and/or lower than expected performance.

There is an interesting efficiency improvement but not tested or proven yet.

In my personal opinion this BE300 is ok but is not a good deal at all and I doubt will rise private pre-orders or other financing options with those numbers, the reward is to low for the involved risk.

If BE300 is what that paper says I think is the end of AM unless a big change in market conditions.
