doGE is nothing more than a meme coin, and it seems like some people have pretty much given up in holding this joke and have decided to dump, it's been going down since last sunday with no signs of recovery. Though i'm not surprised there's people out there interested in a coin with over $1b market cap (but i'm sure most of them not understand how market cap works), and the fact that it still has a "big" community, it is understable that it still listed in some exchanges. Overall, as long as there are holders, I don't think it's going to dissapear from the market for a very long time.
