Dear Customers,
The production of Antminer S1 is discontinued, except for the warranty parts reservation.
Happy Mining

BITMAIN
Holding on to my S1's, hopefully the value will go up again like the Asicminer USB's did.
I have 3 running downclocked and downvolted.
I will hope for a btc price rise to cause an s-1 price rise to 350-400 usd each.
I paid 520usd for these 3 and I have earned .4btc with them.
Every single Antminer S1 ever sold by Bitmain already has made ROI or still makes it.
No other Hardware vendor of 2014 can make that.
S2 is diffrent story. Kinda makes you want S1 design with new chips.
