Incidentally I held off buying the A4 dominator after a spiritual channelling session with one of my guides, dated Dec. 4 2016 (a snippet from the full channeling):
<Are you of the light>
yes
<is my thoughts about cryptocurrency investments good?>
consider yourself limited in knowledge right now... your premonitions are accurate but i consider that
you do not go rushing in right now, physically move.
<are the mining rigs i am thinking of safe>
it will never jeprodize your safety
<what was the 13th of december stuff> <- this was an unrelated issue entirely to Bitcoin or computing at all
that is no longer valid jacob but i consider his advice valid at the time
<are you of the light>
yes
He told me to wait until physically settled, and again until mid January when we are out of mercury retrograde in a diff session. I could not see how I was limited in my investment knowledge, but after reading the Bitmain thing... My guide potentially saved me from being unable to ROI...
This will render the A4 dominator obsolete early in it's lifecycle if it is true...
