UBI is a horrible idea, it just amounts to regular devaluations and redistribution. There's a reason UBI can't be paid with anything scarce or of real value, it doesn't work. UBI is a total scam based on the idea that we can create money from nothing and then spread the money around until we're all the wealthier. Whether you do it with dollars or cryptocurrency its just devaluation and redistribution, it doesn't work and neither do Keynesian economics.
