I believe at some point when the blockchain money is mature enough for mainstream, the central banksters will, with the assistance of puppet oligarch government appropriate (make it proprietary) the technology and proceed to outlaw its use by the public because blockchain technology applications basically will eliminate the central banking system. What may save blockchain money is the development of a real free and independent Internet. A free/independent (not Corporate owned/controlled/monopoly) is possible imo with the launching of a robust perhaps (satellite orbiting) system that cannot be turned off (as dictatorships can with the current operating Internet)
