If you're mining litecoin you might not see a profit, but you have to adapt.  mine other alts and sell at the end of the day for bitcoin/litecoin.  Ignore all the coinwarz type sites and find profitable coins yourself so you can mine before everyone jumps in.  Or better yet, mine dead coins with no difficulty, then wait for them to be revived.  It happens quite a bit and even if the revival is a failure, you can usually grab a huge gain on the hype.
