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.
And the impact is huge. Well, most of us are expected that be going to happen anyway since we know how influential is Elon Musk especially when we are talking about Doge and we also his support of this project. So if ask if investing in Dogecoin is worth it, why not try it at this time but please never think about holding them for long as its price eventually just dumps when the hype is over just like in the old days.
Invest wisely and consider that not all coins are for long-term investments, some are also just for a short period of time.
