Thanks for spreading the word on UBI! I'm a fan.
While the token isn't actually created, yet SwiftDemand is similar to mannabase and is awarding distributions. I won't post my ref link here since it's your post :)
I can't get manna because of the cell phone requirement.
Also be sure to check out @steembasicincome. It's not technically UBI since you have to buy in and be active, but it has many of the same concepts.
