Doge does not have any team that is managing the concept of development, no roadmap and it was just created for fun. Besides, Elon Musk is just messing around the crypto space, John McAfee did more than this in the year 2017 with his coin of the week manipulation tactic.
I wouldn't dare to compare these two guys, insane McAfee and Elon are two different worlds. I think Elon is having fun, but in the same time he probably have his reasons for supporting crypto, especially Bitcoin and Doge.
Good marketing for crypto, and this is not the end of it. Elon is making some interesting moves and I think he will continue with surprising us. I guess we will see a lot more from Elon in the future...
Where is McAfee now, and his coins, exchanges...
