It seems so hard for me to determine whether any of the Altcoins will ever become truly worth mining or worth owning in general. Now I did witness Litecoin make its climb earlier this year and I did make my early, yet tiny profits from mining Litecoins with my 7950 and buying them also, but I just can't tell what is speculative "pump and dump" and what's not. It's like, I've heard across the forums and websites that PPC could be "the next Litecoin" and how it how has certain special characteristics, such as being a proof of stake coin, which "will" make it profitable...but will it? Is it all just speculation? On the other hand though, I've also read that cryptocurrencies in general are the future, not just Bitcoin, and that, in and of itself, will make most of them worth something.
