Mining is in a tough spot right now.. I've been doing some calculations and for the most part if you want to come out ahead.. It just better to buy the Bitcoins and hold onto them

Here is a fairly accurate estimate of what you might make mining with the following parameters

If you want a faster or slower speed you can just divide or multiply the results

The thing is if the miner you want to buy is more than the BTC listed here.. You're better off buying the coins

Bitcoins Mined up to = 31/12/2014

Speed = 1000GHS

Power Cost = Not Even factored into these calculations because it's different for everyone

Average Difficulty Increase over the entire period

10% - 6.68643026BTC

12.5% - 5.76693502BTC

15% - 5.04956851BTC

17.5% - 4.48134362BTC

20% - 4.02480813BTC

22.5% - 3.65311067BTC

25% - 3.34673347BTC

If you want to estimate there will be a 15% average increase then if you paid 5.04956851 x $445 (Current Rate) = $2247USD you would break even on the miner itself.. without factoring power costs..

Unless my calculations are off this is quite depressing

The numbers look even worse for the Spondoolies group buy that just finished also

Of course if the BTC decides to rise then these figures become much more favourable...
