Where I think the two (UBI and cryptocurrency) align is in a platform like like this (steemit). I'm totally new here and essentially a noob at cryptocurrency, but as far as I can work out this Steem currency is being created (edit: I don't think that part is true, after further reading) and distributed where the community most sees value. Keep in mind this is how a regular fiat money works, except that regular money is brought into existence as debt (see https://politicsforpeoplenotcorporations.wordpress.com/2016/10/28/the-economy-is-a-ponzi-scheme-no-really/), which requires a never ending run of borrowing new money into existence to meet the interest payments on that debt. Which also promotes financial gambling. But we need new money created to more or less match the value that is added to society. This Steemit model seems like the perfect way to create new money for valuable contributions to society. The link between UBI and Steem is not direct, like others have pointed out above, due to the fact that UBI is supposed to be unconditional (i.e. you don't have to technically provide something of value to society for it). The link is more indirect and centres around the novel approach to money creation that Steemit uses. A UBI could be funded by similar mechanisms, but instead of each individual explicitly showcasing their value to society, we should consider that each individual automatically and inherently adds a certain minimum amount of value to society. That value can be recognised with new money created in a similar debt-free way as Steem is (well, as far as I can tell how it is created).
