I asked gtg about it and he said the only way it'd be feasible here is to do it on the blockchain as a feature of our coin, which makes sense and I think has been proposed by some others who want steem to be on the forefront of UBI. Personally I just have a list of autovoted persons for now, I asked mahdiyari of steemauto if he could implement something that would give a balanced amount of VP per day to everyone on a list and he said he could work on that, which I was extremely grateful for and will use immediately once it's out.

I looked into manna, I can see why they would want everyone's address to make sure people aren't UBI farming with multi-accounts, but I'm not sure I'm comfortable with a program that seems to have such an emphasis on a referral program (which skews the income to the spammiest people or those with already large social network reach, which I don't think is what a UBI should really aim for) and physical location data gathering, among some other things that make me go hmmmm. There are some other UBI coin projects out there and I should probably research them heavily, I do not like shilling coins or icos and would feel terrible if anyone got their security compromised etc. on one of my recommendations through a leaky wallet or something.

Yeah, there have been some, but my SP isn't attractive enough to make a lot of them reconsider their actions, or maybe they don't understand what I'm trying to say.
