WTF? Diff Increase 30%?
some more such increases and i have to sell my S1 Antminers
damn electricity prices.
dude! haven't you seen what is still to be delivered? network hash rate will probably double by the end of summer.
I retired 18 Erupter Blades a few weeks ago and my S1's will no longer be profitable soon as well. The blades were running since September of last year and did well, the S1's covered their cost and just a little over. It makes me wonder how the guys who spent >$2,000 on terrahash units will be doing in a couple of months, do you think they'll manage to recover 50% of cost before they are fully depreciated?
Are you looking to sell any of them? Electricity doesn't cost me a thing so I might be interested.
I dumped them all on eBay. I paired them standing them up in an old ATX motherboard with a 350 watt power supply for each pair, advertising them as Bitcoin Starter Kits. All nine pairs went with Buy It Now purchases in 24 hours. Suckers...

Even if electricity is free your time is not, and I don't know about anyone else but a pair of these takes too much attention to run for a month and earn a measly 0.01 at the next jump.
