I think there is great potential with litecoin, BTC-e's deposit methods are v restrictive which makes it difficult for most to invest.
it has already surpassed 300% for early adopters. if you got in before march you have already made a lot. problem is; its just a copy of btc with holes in it and there is no development behind it to improve upon it. their own wiki states it is a pump and dump scheme. not cool guys.
however, i own a small amount, purchased at 4 cents, and i will hold and see. the fools could help me translate my already huge gain into even more gain which i will then convert to btc. if it tanks i wont lose a penny cuz i already cashed out my original investment.
if you want to emulate this process, buy into ppcoin now. after the manipulators are done raping ltc to death, they will do the same thing to ppcoin (then ftc, then nmc, then w/evercoin)
