He's never paid to do promotion of Dogecoin and what's the reason? it's simply because he's a bagholder of it. He holds a lot of it and that's how he's determined he was in promoting it through his X's profile before. Maybe we're going to see him advertise it again since he's now known that he's probably holding more of it until the bull run comes.
I think people who are good in understanding his kind of manipulation will definitely embark on purchasing some Doge coin. Yes, it may be like you said watching out for the bull run so one little promotion can send the price skyrocket.
So it's no surprise now with X,If you want to get more things at X, then you have to pay, which was previously free, because he really wants profit.
so I also doubt that he was with the dog.I believe the same as the colleague above: he will not do any promotion for Doge, because of how much he has to be paid because he only thinks about profit.but he manipulated his way in order to profit from the doge, and he did, and that's fine, but I doubt he kept the doge for long.
