I don't think it was ever intended to last indefinitely but just was a pilot.
As for the rest, there aren't many countries that couldn't in some sense benefit from a basic income at least in some ways, only countries with actual full employment as well as no serious poverty wouldn't and those are few indeed. Basic income is experimental for sure, hard to say how it would work on a society wide basis, lots of unknowns, but it isn't abandoned because it has failed or anything, that's simply not true. It has usually had some positive effects where it is tried but it's usually a limited trial. It isn't something proven time after time to work well like single payer healthcare or something, it's still in beta.
