The real trouble are the whales: https://bitinfocharts.com/top-100-richest-dogecoin-addresses...
The biggest walket owns a quarter of the coins.
The Top 100 own over half of all coins. They can send the price down as much as they like.
And then the question is, well, is the coin more or less valuable when it is held by more people? It seems to me that it would be more valuable, since there would be more people using it.
So even if the immediate effect of the whales cashing out was to lower the price (to something above absolute zero, assuming there will still be buyers), the long-term effect would be more adoption, and increased value.
I'm sure there are holes somewhere in that logic, feel free to point them out.
