I think DOgecoin could reach $1 in 2022 for various reasons especially the biggest Dogecoin fans and holders don't make instant sales as this could result in Dogecoin losing 50% of its current price. and I also believe that Tesla CEO Elon Musk will try to make the price of DOge increase as rapidly as it was mid-2021. everything happened out of control.
That is highly unlikely.
I don't think that Dogecoin will be back to its former ATH. Although the possibility will remain there but going back there needs a very tough pumping and influence to be done by ELon.
He's the one that has been encouraging people to buy this meme coin and to think that it will be on $1 is already too much. $0.7 or the all time high of it was a success and it's one of the impossible things to happen yet it happened but, I think that it's already beyond if it happens.
