I really doubt Elon Musk, whether he really bought Dogecoin or just promoting it so that the cryptocurrency could be popular,
there is no evidence about Elon buying Doge, but evidence that Elon buying bitcoin is true, whether this is Elon's strategy or something ?
but this is a good thing, i shouldn't care if elon buys doge or not haha, the important thing is he makes us all have a lot of profit from his tweets
