Again this is assuming the price of LTC also does not increase. That is unlikely if the difficulty increases.

That's true. It would start being worthwhile at around 70$ (maximum price was iirc ~48$ recently). It may be very well possible to get an return especially if you believe in litecoin (328 times increase in 2013 [1])
