You can say doge might be just meme coins that was created based on joke . but doge has been with the crypto community for a very long time. and I myself am one of the doge users who used to be just for fun. and used for microtransactions. after the pump from Elon which made the doge look like a bubble scheme. and to be honest I've never taken coin memes too seriously.
Well, mostly people here didn't take any meme coin seriously since it didn't have any real use case but i don't say it was bad too, As you said doge it's already on the market very long and it's also become alternative coin to sending from exchange to exchange since the was really low but for now i think most of meme coins it just some pump & dump scheme.
