All I would say is that things take time. The internet didn't take off until many years after; how many people can even understand the blockchain, lest code actual working products for it? The technology is still in its early infancy and only the greedy are impatient for high returns. To put things in perspective, who would have known a perfectly good company like netscape, which has browser dominance, to disappear or myspace to be totally eclipsed by a more superior facebook?

Same thing for all new technologies: it just takes time.
