I think most people miss the ever increasing difficulty factor. I've paid as much as $20 and as little as $5 for block erupters. I have 100 cranking away along with some Blades. I've made my investment back but now that I'm in the profiet area the difficultly is so high I'm making 45% of what I was just six weeks ago.
I wonder what I could get for a 100 stick mine turn key?
If you were to list them on EBay Germany, you'd end up with approx. 5000-8000$ within days o.0
At least here, practical non-availability of literally
anything at reasonable prices is what is making people buy it for "too much" (lacking alternatives, count me into that group :p )
What I also see lacking is "in-between" performing hardware, it's either the old hardware or buying big into Mar/Apr 2014 stuff with unknown outcome. Inbetween, there's a hughe gap.
