surely the recent bullrun that this coin have is caused by elon musk, he's the only one that could make such bullrun in the first place after all, moreover so many doge fans I think are thinking that if elon succesfully owned twitter then eventually doge will have some use to the platform which actually is still full of doubts, since elon surely have his own vision in term of growing his twitter platform, that could be the determining keys whether this bullrun will be long lasting or short lasting ones.
What is interesting of all of this is that those which are investing in dogecoin thinking that Elon is going to implement it on Twitter still have no solid evidence this is going to be the case, it is true that Elon stated this was a goal of his but that was before he owned Twitter, now that he is the owner he does not need to actually follow through with that vision if he believes this is the wrong direction for Twitter, so if at some point it is announced this will never happen the crash dogecoin will go through will be massive.
