I'll sell you one for 0.12 BTC + shipping and walk you through setting it up.
I see people using these hubs and stuff, for multiple ones. How hard is it if I bought like 9 of them, and hooked them up to run 24/7? Will it work on an old computer? And how much startup costs? I have the computer, thats all.
If you had 9 of them running 24/7, you'd mine about 0.09 BTC a day (from what people elsewhere are telling me)
Not sure where you get the .01 a piece, more like .003 each.
As difficulty goes up, your return goes down.
Current difficulty is 148,819,200, and 3 months before it was 12,153,412
(https://spreadsheets.google.com/pub?hl=en&hl=en&key=0AmcTCtjBoRWUdHVRMHpqWUJValI1RlZiaEtCT1RrQmc)
So, your daily return could have been 10 times more 3 months ago.
From another viewpoint, in 3 months, your daily return "could" go down to just 10% of your current one (if difficulty keeps going up at this pace).
totally changed my mind, I wont be buying these
That's why the price of erupter crashes from 1+ to 0.1 BTC now.
