The crypto market is unpredictable. No one can guarantee that a certain coin will skyrocket sooner or later. And there are a lot of factors influence the price of DOGE like Musk's tweet, for example. I store some DOGE on my OWNR wallet, I'm not going to sell it in the nearest time because I believe DOGE has a great capability.
I see DOGE has a more stable price if Bitcoin does not increase at all. So Doge coins are good for you to invest in for a long time because you are not surprised by the decline in these tokens.
