IMO, moving forward, I don't think elon's influence will mean that much, the only thing that can help DOGE to go up again is the hype from retailers and also the altcoin season narrative once it kicked up.
DOGE is the biggest meme coin by market cap so it is to be expected that the rally can be pretty slow.
honestly it'd be great if even DOGE can also got approved of ETF although it's unlikely.
Things will change quite a bit, now that Trump was elected president again. Donald Trump often hinted he will nominate Elon Musk for a government position. Musk used to say he will establish a D.O.G.E. (Department of Government Efficiency). This is an indirect reference to the beloved "meme" coin. I'm sure market prices for Dogecoin will skyrocket during Trump's second term. At least, within the first year.
Anyhow, Elon Musk is only into DOGE to make a lot of money. It's very inexpensive. Therefore, easier to manipulate. Once he gets tired of it, he will move on to the next big thing. That will leave DOGE alone, dusting in the corner. It's the same fate that awaits other "meme" coins. They're speculative by nature.
Always remember utility is greater than hype. We should focus more on useful coins such as Bitcoin, Ethereum, and Litecoin to build true wealth in the long term. As for Elon Musk, I wish him the best of luck on all of his future endeavors. With or without him, crypto will carry on as usual. That's the way decentralization works.
