since there are so many miners here and I want to buy ANTMINER S3 I'll post my question here. Is there a chart of multipool mining profitability in fiat over a long period of time (6-12months)? If not maybe you can tell me from your experience..
I want to know whether the current $1.6/100GH/day is somewhat stable and can be expected to stay that way the coming 6 months.
(I'm a newbie regarding mining, so with this miner I can use it for multipools right?

)
No, it won't. You can expect the income (in BTC) to drop 20-30% every 10 days or so. Go and read up on 'difficulty'
Whats this 20-30% witchcraft?
I see the last diff jumps were 3% and 8%, Here's hoping they stay around that rate!!
Bitcoin Difficulty: 18,736,441,558
Estimated Next Difficulty: 19,526,251,935 (+4.22%)
