As a Batch One customer, I fully understand the anxiety and frustration of watching my BTC ROI dwindle as difficulty rises.
Of course ROI in fiat is an entirely different story and a source of much consolation.
500GH per second is an engineering fact, not "marketing" BS.
Another engineering fact is that only a finite and very limited number of Batch One chips exist.
HashFast cannot use magic or wishes to create more, so shipping extra capacity is impossible until more chips are ready.
MPP chips have already been paid for and are being fabricated.
Once our production line is complete, meaningful estimates for MPP shipping dates may be anticipated.
While it has been a long process, we are nearing the end of the beginning!
