We can't point out why but for a common understanding it possible because he easily manipulates Dogecoin compared to others or he might be a part of this project a long time ago. But the question is if the people have an interest in Doge? Those who follow and trust Elon might say that they are also investing in Doge but I could say to them that they need to be cautious and need to understand what project they are with. And I would also say that don't put all their money on Doge, coz I'm afraid if Elon is just playing and fooled them.
