So you wanted to start a discussion, but it is always hard if it's not about some hyped coin.

That's why I decided to share my opinion.
I like DigiByte (though I never mined/traded it), because to me it seems like one of the good coins out there (and I will always support them in some way), but your bigger problem is supply.
Coins with billions in supply are dying imho. I'm not a coder, but I know that forking it could cause really big issues (giving the network you have) so I think you currently are not in very good position.
P.S. Most of the coins don't have different approach other to be cryptocurrency (fancy wallets, features etc..). If you make something really unique, maybe you can succeed.
That's my honest opinion.
Cheers,
