Apart from bitcoin, I know few other crypto currencies (by this I mean currency which works in a similar way to bitcon). They are:
- namecoin
- lightcoin
- ripple
I also heard about SolidCoin, but as far as I understood it is already dead.
Is this everything or am I missing something
1Not that I can think of. There are a lot of websites that claim to be about an alternative cryptocurrency, but are actually spam or one-man-projects that never took off. – Steven Roose – 2013-05-02T23:57:57.590
