The only alt-coin I have faith in is Litecoin.

I have about 500 LTC stashed away in the hope that they someday become the silver to bitcoin's gold. 

Saw a little spike in value with yet another rumor about LTC being available on MtGox, but then everyone lost patience and it's back down to around 2.5 USD again.

Long way to go before I make up my losses, since I bought in at 3.8!
