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.
If Elon still supports doge and uses doge as a payment method for his companies, an ATH of $1 is possible with doge. Doge could still go back to $0.01 but as long as Elon backs it up, it won't be forgotten and die prematurely. once doge dies memecoin will not be able to survive in crypto. I don't think it's possible.
