I don't expect much growth in price and adoption for this coin but they've some a long way from being just a meme coin. I'm surprised that they're still around to be honest and kudos to them for outlasting many other early cryptos. I guess many people still finds value in them like the faster confirmation and cheaper transaction fees compared to bitcoin as you mentioned.
Exactly, they've grown so well that gamblers prefer dogecoin because fees are low and faster as well. So they can still exists in this market and won't simply disappear. As far as listing though, probably we will see them listed Coinbase. I mean they are still in the radar for some investors and we don't know, maybe it can also enjoy the support later when go on a bull run next year. But I'm glad that dogecoin still has the reputation now as not just a meme coin.
