Elon is an arch joker, he just likes slapping Dogecoin about and flexing his ego by pushing markets about ( or trying to).

I shouldn't complain, his first foray into Doge pumping made me enough to buy a new phone, pity I didn't wait a month or so longer I could have ought 10 !

There is something distasteful in these games to my mind, on one hand it can be viewed in a light hearted manner, on the other hand it IS serious market manipulation akin to any pump and dump scheme
