If this will be over, and I don't know if Dogecoin holders were still able to keep it on their hands or they will sell and dump it.
The problem with Doge is quite simply that the Elon hype has caused a lot of people to jump on board who have never been in contact with cryptos before and have at most read about Bitcoin in the newspaper. If you look at the Doge chart now, you can also see that a lot of "newcomers" have burned their fingers with it and will certainly not come back so quickly.
