ok, now I am running profitability estimates using the Antminer s-3 numbers and my local power costs. Very interesting, it seems the concept comes down to converting electricity into Bitcoin. The following parameter has me confused:
---
Difficulty override
The estimated difficulty change from BlockExplorer is used by default. Enter a percent value here if you want use a different one.
---
Their default is -6.1% change in difficulty but from what I hear difficulty goes up not down. On the TradeBlock chart difficulty recently jumped rather largely. I replaced the -6% with a +5 and can see that the prediction is for declining profitability. +10% is definitely trouble. I will keep on reading but are these estimators accurate? What % makes sense to plug in?

diff jumps calc at 8% 10% 12% 15% 18% 20% 25%
at 25 no go at 8 yes. the real number
my guess is 14 to 18% right now buying to mine does not look as good as buying coins and holding.
the mining game has a lot of factors.
s-3 is a nice space heater in the winter.
do you have noise tolerance?
a place with some cheap power.
etc.
