I think this coin may have a chance to revive if we want... I have looked at the code and the changes made to try and fix it. Nothing significant was done, I don't see any real effort to adjust the numbers and make the chain work, all I see is a bunch of version number changes and stuff that wouldn't affect PoW end PoS start.
if that's the case then dev was not a good coder, just another copy and paste dev. if this coin wants to revive then it needs a community takeover.
