Every person has his opinion... Your experience and the knowledge will help you figure who is the next king! The sure thing is that the throne is made to be sited from different kings, If we look at the history, to become someone the new king means that the old one is dead. BTC isn't close to dying so we can't do any forecast. Maybe a good research will drive us to ETH but still, it is so early to talk about new kings.
EDIT: that was a reply to the post and not an answer on your coment! i did it by mistake.
