With $5/day you can rent an up/down townhouse in Asia/Africa electricity included (if not using A/C).
Steem isn’t UBI though. Mannabase is (but there’s no incentive for investors so far). Steem is an active earner (for freelancers). More so, Steem is a new economy or has the potential to become an integral new economy.
Steem can change social vertical mobility, now already. That isn’t a factor in UBI. Two different things.
Steem is an option to compliment UBI. A very compelling one, no matter where one is based. Most paid bloggers never make what they can make on Steem. Just check fiverr.
Anyway... now the question is how to get that pitched with Gates. He hasn’t seen the lightbulb go on yet. ;)
