I think this is only temporary, maybe the increase in doge is just because Elon did something about this meme coin. this has nothing to do with the future of crypto as doge is just a meme coin that has no utility. There are still many altcoins that are more worthy of being said to represent the future of crypto such as ETH and BNB or Bitcoin itself.
If we look at the trend for meme coins, it is clear that many have doubts about their inherent capacity. More meme coins are detrimental for investors who really hold on to them. But for Doge, there is an exception because this is a coin that has been around for a long time and has been very tested to date, and it must be admitted that Elon Musk's role has really influenced Doge to be able to survive until now. But if you really want a short-term investment, I think it is very possible to do it with Doge, but I doubt it will be held for a long time because, as you also said, meme coins are very susceptible to changing quickly. For doge, there are exceptions, but remain alert to pay attention to their movements because something undesirable could happen.
But when compared with other altcoins, which are in the best position currently on CMC, it is clear that it is better to keep other altcoins compared to Doge. Obviously, it would be less worrying about significant changes occurring than holding doge. but everything is returned to us to be able to analyze it well before deciding.
