Thanks so much for your informative comment. I hadn't heard of circles but will check it out now.

Yes, I think crypto provides the greatest likelihood for UBI succeeding, and Manna does need to start getting used. But their tech isn't quite developed to that point yet, so I'll be patient. We Steemit users have gotten spoiled, having an actual platform for our trade of STEEM. No other crypto is actually functioning as a platform right now, that I know of. Everything is a promise. Except I guess Ethereum, which so many ICOs are using for their smart contracts as ERC20 tokens.
