If you could convince someone to sell you a box full of Block Erupters at about $1 each, then they'd be great. At about $5/each, they'd be so-so (and still about to be obsoleted, cost-wise). Anything more than that, and they're just not worth the cost anymore.
But people are still willing to buy them, which is where I see the value. I picked up 10 of the .333 asics the other day for $15 each. They are going for upwards of $40 each where i live, sure i could unload for $30 or so.
I'm trying to figure out what the re-sale of antminer sticks might be a month, or 3, or 6 months from now. Will their value still hold going forward?
