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.
You are right. Doge has hang around for quite a lomg time and has never dropped a quality one bit. One of the best Coins with the cheapest transfer fees out there. Its the largest community coin i know and i wont be surprised if coinbase chooses to list it based on this merit just like Binance did. I do hope they can be more than a meme coin though and advance technologically too
