Dogecoin, an utter joke, always has been, always will be.
At least is still decentralized, and the inflation rate is known. There are several worse scams in the top 10 cryptos, not to say of the rest.
That said, the mass will be always scammed, in one way or the other. But being scammed with shitcoins is an huge progress because it's voluntary, so it teaches responsibility and it let ppl's awareness grow instead of being reduced to spoiled brats of the government.
Doge isn't a scam. It was incepted as a self-aware meme. And frankly speaking I'd be more willing to use Doge than fiat currency if the infrastructure existed. I wouldn't throw money at it, but in the case of a binary choice between fiat and Doge where Doge could be spent just as easily as fiat I would go with the latter any day.
