I will advise this thread be moved to speculation board or altcoins discussion, because it has nothing to do with the forum, but cryptocurrency at large.
To answer your question, we are going to first consider on what we have on ground, how is it recognized, acceptable and useful for the immediate challenge the world is facing, which i don't think there is a precise innovation now on ground to stand the gap of what cryptocurrency has made, except on other aspects other than digital currency, taking about quantum and the likes, they are coming up on a different pace to what we already had in bitcoin.
