The idea of a guaranteed income for everyone is a good one, but a cryptocurrency can't guarantee that. There would have to be some sort of real-world agency that verifies people's identity and ensures that only one wallet is given to each unique individual. As soon as major money is involved in this universal income scheme, Facebook wouldn't cut it anymore.
I think that you should strongly consider ZenithCoin. It's rarer than a lot of coins (not in the hundreds of billions) and supported by an active community.
I registered on the site and voted for the coin. I'd post a screenshot, but unfortunately it seems that there isn't really much visual evidence that I've voted for any particular coin.
