Just thinking about switching currently my computer is worth about 4 bitcoins a months so about $300 a month before electricity, i could mine 527 lite coins (minus pool fees of about 4%). If litecoin picks up to become a competitor or an alternative to bitcoin I could have a small fortune like many bitcoin early adopters. Might be worth the speculation just for a month. Idea would be mine litecoin for one month of the quarter then mine bitcoin the rest to pay for electricity and other household cost as it is at the moment.
