I was going to upgrade them but decided it wasnt worth it. I have a s2 and 2x s1's should I just sell my two s1's on ebay? as they dont seem to be making much compared to electricity. Especially with drop in BTC price.
any advice would be helpful.
Mine is still running. I undervolted it, got it deep in the basement and it's mining because I don't feel like pluggin it off
. Well, maybe it is time to put it on ebay but hell, I just like the idea of home mining.
