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.
