DGB has nothing much that a lot of alts.
It is a bit too hyped. One alts like DGB but much less hyped & overpriced is without a doubt Okcash.
Like DGB, it has lightning transactions, low fees and no scalability problems.
I think DGB has good development and the trading volume is also high.
It does, but it's one in a million.
There are plenty of altcoins with good development and a high trading volume. Digibyte isn't special enough to be worth a lot, and people are starting to realise that their faith in barely useful alts is pointless.
