@liberman, Protoshares are quite special! Haven't you noticed the rise of it, yet? It will (IMHO) surpass Bitcoins in value, hopefully, IF things keep going the way they're going!
Protoshares are not only a Bitcoin-like cryptocurrency, it's far beyond that! Right now I'm broke as hell, but if I had at least $5,000 I'd definitely inject more money into III! I promise you, if you're patient enough, you'll be more than happy with what you can get from these projects!
