Exactly this.
But it is strange, when you know exactly the total cost of your product, when changing the final price, means:
-Cost changes on daily basis
or
-Markup on cost changes purposely on a daily basis
I cannot believe that their cost changes on a daily basis.
I think it is most probable that they decrease their markup daily.
I cannot understand , though, this strategy.
The cost of an iphone is 10 usd per piece that is what apple paid foxconn.
The bulk of the 199-10 = 189 is in paying for marketting gurus and r&d engineers.
The cost of building electronic in china is simply unbeatable an antminer s2 will cost no more than 500 usd to produce. The PSU cost is actually quite large in proportion to the hashing boards, add 150 usd to that 500 still cost 650 maybe, they are doing what a good company should be doing that is value-based pricing. There were people who'd pay 3000 usd for s2 back in march, their batch 1 sold in less than 24 hours why sell for less ? Maybe should've asked for more... as diff increases they can lower it bit by bit and still profit.
Remember they're still using the 55nm chips, and who knows maybe they populated them in a huge board to test run it for a month before repopulate them again into s1 and s2

double time.
