I don't know if DOGE prices will go up or down in the future, but I've definitely seen a lot of volatility with prices lately. DOGE's next high could be much lower than its current price of $0.068.
If you look at Elon Musk's dream to make Doge an interplanetary cryptocurrency to support the interplanetary commerce mission. DOGE-1 will be a very important event for DOGE.
Anything can happen with Dogecoin. I would imagine that ATH $0.74 will be crossed and is still a likely scenario at some point in the future, but who knows what will happen if there is another sharp spike in price.
Since it's didn't have any real use case so we only expect some short run like before when musk and other public figure tweeting it.
