For customers receiving units before October, we will adjust the price of your machines consistent with the 4.5TH/s +- 5% hash rate. Compensation will be based on preserving the $/GH ratio of the original deal. Starting in October, we will compensate you for the differential in hashing power according to each customer's preference. We will contact each and every one of you over the next few weeks to discuss your preferred method of compensation.
Early thoughts likely to be amended....
Whilst I appreciate that you will compensate buyers, $/GH isn't the only factor.
They've gone from 0.4w/GH to 0.67w/GH which significantly impacts both the running costs AND the length of time these will be viable to run.
