I guess i'm still pretty new at this but I'm not really sure you can trust any of the ALT coins. BTC, LTC and PPC seem to be the only 3 worth putting hardware into.
The only one which have real potential is BTC.
LTC is something like sub-economy for btc, but very small and no real potential to grow. Maybe it works fine just as it is. Anyway, wasted time.
I guess, although that tune might be changing when ASIC miners start pushing GPU miners out of the ring. LTC will be where they end up me thinks. /shrug I'm new what do i know
