I received the chips from Zefir for batch 3 and up.
I have not received boards from Sebastian's Batch yet.

Once the chips are in hand of my contractor there is not much i can do to accelerate things.
And this week they were down to 1 Machine because of maintenance.
I initially arranged to use 2 contractors simultaneously, to deal with the large number of boards.
The chip refunds cut the board volume to less then half, I had to scale the operation down to reduce costs.  
That also included the shipping contractor.

Regarding bitfury:
I have an exclusive agreement with cryptx until mid October.
Revenue i get on that deal will end up in the refunds.
My 50% refund offer exceeds my current available financial resources.
(all Paypal payments are unavailable)
The refunds are currently suspended because of that.
But I will stand by my word and carry out the 50% as soon as i can.

To any of the "he gets rich" screamers - revenue of this venture so far: about -20.000eur + 4 Months of Work.  
Not that those people will believe any of my words.
