Litecoin is, like any other alternate cryptocurrency, just a scheme to steal the BTC from clueless newbies.
Can you explain me what you saying?
Are you telling me that I should mine BTC with my NVIDIA GPU, dump $$$ in new rig or something else?
I'm saying that dudes like you only want BTC in exchange for the scamcoin they mine, and eventually the scamcoin you are mining will die, and the persons to whom you sold those scamcoin will be out of their BTC.
But by all means, keep at it. Mine scamcoins and dump them, I'm not the one who's going to lose my Bitcoin anyway.
