I don't disagree that it's extremely unlikely that certain governments will adopt it, at least not without lots of other governments to point to as success cases at least.
I'm just not sure how it's feasibly funded in any other way. That's the main problem as I see it. Any non-governmental body can't actually fund it to any degree other than as an experiment for a subset of people (which has happened, from HN no less[1], but I don't recall the outcome).
Maybe, possibly, a religious organization such as one of the various Morman churches that strongly encourage tithing could do so, but it would probably be cast more as charity than UBI. That's also ignoring all the other problematic aspects of something like that.
The other innovation of cryptocurrencies is bootstrapping 'value' for scarce digital tokens; in this sense, UBI based on a cryptocurrency can be self-funding.
That only works because of investment and speculation. You would specifically not want that for UBI IMO, because speculation could crash your currency leaving people that rely on it unable to purchase anything with it. I'm pretty sure you would need to tie it to a stable real world currency for it to function for its intended purpose as a basic income.
