Sure, but they weren't known when burnin estimated EUR 470, so quite possibly he was using a lower price in his estimate. Also, you need to order at least five reels (of 3,000 chips each) to get a discount - so maybe, maybe not - that's quite a lot of chips to order up front. And lets allow cyrptx the 10% markup on the chips that we allowed zefir and sebastian.
I assumed this before
When I get all this right, Burnin stated his first price before Bitfury raised the price for their chips by 50%
I don't think so.
