In no case do I think the scam was premeditated or that anyone other than FC was involved.
I know there can not be any proof for this claim, but would you disclose any logic behind this? What makes you so confident to state above?
It just doesn't add up. Why do you think they stopped new amhash sales around the time the hardware was supposedly stolen? Why did AM offer full refunds/replacements to those with defective prismas? Why did they even bother to set up a datacenter and back all shares with real hashrate?
You could argue that this was all done to paint the illusion that it wasn't a scam, but I just don't see why the guy who earned 10's of thousands of btc legitimately would scam the community for another ~1.5k btc. (though I admit it is definitely possible)
As for FC being solely responsible, is there any evidence to suggest otherwise? So far we've seen several insiders share their point of view about this debacle and they all point to FC (and his disappearance) being responsible.
