Well, if you would not recommend Fairbrix... then what 2 or three types would you recommend besides Bitcoin?
This is purely my personal opinion, but the one I am involved with is Litecoin. It is unique in comparison to the others in that it has no "pre-mine", the creator didn't create coins for him self ahead of launch. There's more info on
http://litecoin.org/.
That's the only one I'd recommend right now, but I'm heavily biased.
