Yes, it is a scam! You need to stop fooling yourself here. Ask yourself how long it took from the first 'working' video of the X1 and when paying customers (not David, a BA spokesperson) actually received it. O wait, I still haven't received my batch 1 order for X1s from Blackarrow. They refuse to say if I am on this mythical 'refund list' and they have not shipped anything. So, good luck with your 'proof' of X3 existing and shipping next week.
I don't know what you see, but what i see is a machine runs at 1.07 TH/sec i bought several X3's the should run at minimum 2.00 TH/sec...i did'nt see that, so who is talking about an X3???
