I can not say anything about this fork, because I'm very negative about projects of this kind, I simply do not understand their need for people. The same can be said about BCC and BTG, they in my opinion are not needed.
It's true that there's been a lot of useless forks around these days. Bitcoin Atom for example.
Still BTG is good as it is veery suitable for GPU mining.
What is BCD good for, I don't know.
By the way, their site wasn't working when i tried to hit it.
