Ok. so as in regards to pricing:

I am assuming that when they laid out their initial pricing the bitcoin price was about $150 USD, now that they have watched the price per BTC slide as we have been salivating over the increasing deal, they have been worried. so I am confident that the switch from BTC to USD was a financial one. With that said I am sure TH paid more in dollars for their first order of chips than they will for their second order. So when we calculate their cost of materials one must use the cost of the chips at the time of order not the cost today.
I for one will be using BTC for the 5% tomorrow.
