I don't think it's dead. I remember when DOGE was trading for like 28 sat and people were saying it was dead. But DGB has a lot going for it, as far as I can tell. I think there was some over-exuberance that put the price over what it's worth, and we're seeing a perhaps equally irrational correction. But in my estimation it does have value and I do think it will eventually be a $1 coin. That could take a long time though, IDK.
People say stuff like "Bitcoin's great but you can't buy a cup of coffee with it." Digibyte is the kind of coin you could buy a cup of coffee with. So that's gotta be worth something.
