Litecoin difficulty is now up to...  5162!  ...with a network hashrate of 173GH/s, and only projected to continue rising higher.

That means approximately 0.18704355 LTC per MHD, or 0.00513434 BTC per MHD at the current exchange rate before fees.

Assuming power requirements of 500 watts per 1 MH/s for GPU mining, that brings the breakeven point (not considering fixed capital expenses -- e.g. your equipment), to 0.00042786 BTC, or US$0.2674 per KWh at the current exchange rate before fees.

Do you know how much your electricity costs per KWh?  Or how many MH/s you generate per KWh?  How much higher will the litecoin difficulty be in 2-3 days?  (And how much lower the return per KWh?)  How many will you be surprised at the end of the month as to how little of it you get to keep?  The only GPU miners still running after the shakeout may just be in the bedrooms of children still living with their parents, in college dorm rooms, and on the sly in office buildings.  Who will survive?!  These are very interesting times!

Tune in next week for the exciting conclusion.  Same bit time, same bit channel...
