first, 950 donot include psu, second, this price is only for foreign customer, bitmain need add 17% tax for Chinese customer, so they canot set the price as 950 for me

BTW, i will pay the compensation to the next diff now,  the next diff should adjust on 8th Feb， so total 12 days from 27th Jan. according to 100%pps, 0.0042 btc/T/day, so each s7 will got 0.0042*4.73*12=0.2384 btc

will send to the btc address of each customer who buy the s7 in this batch.
Update: sent
