I just read someone's post if Elon promised to change the Twitter logo to doge, if this is true of course in the future there will be a significant price increase in the price of doge.
that actually has already occurred so its not a promise anymore and indeed the value is increasing quite significantly, meme coin is always fueled by shills, it's not utility and real use case that helps them gaining new all time high but shills and it seems shilling that comes from famous figure like elon really being valued so highly by the meme coin community.
