I consider Dogecoin to be the top name when it comes to memecoins and while many new memecoin projects already lost their traction and may have been gone to the kingdom king Dogecoin is here to stay though I am not expecting it to travel to the Mars soon. Yes, it can still be a good asset to add to one's portfolio while waiting for it to double its price which may happen in 2026. right now, Dogecoin needs some excitement but Elon Musk as the excitement provider has already tamed his appetite for Dogecoin as he don't want to be accused of manipulating the market. So if one is willing to take the risk Dogecoin may still give us some mild returns but definitely not anymore the x10, x100 or x1000 potential as those belong already to new breakout projects.
When it comes to memes coin, what first comes to my mind is dogecoin because I believe it to be the first memes to have existed before others. The wave maker as you have said Elon Musk seems to have made some adjustments from the memes since he was appointed to head the Department of Government Efficiency. Although he is not been actively involved in anything crypto since his appointment in order not to cause any crypto-related scene so that he wouldn't be labeled as manipulating the market but his department speaks of many volumes to the crypto community.
Everyone must admit that, when talking about meme coins, what comes to mind for many people and the community is the existence of doge, which has given a big wind to the movement of meme coins so that they can be known and many try to follow the role but cannot.
Of course, this is good news that you convey that if, indeed, Elon can continue to contribute to meme coins, of course, it will be welcomed by many people, even though not openly because of the influence of the position he is burdened with.
