The Darkcoin is supposed to have anonymity. The devs did the work and the product has value. And it makes sense to do PR as well for the product.
On the other side, the Anoncoin does not have anonymity. It has only a lot of months of promises. There is no product, so it is tanking. Who is going to promote coin made of promises?
I worked many years as a SW developer and I bought Anoncoin on expectations that I will invest my work into Anoncoin. I offered help three times but guess what? So now I have lost significant portion of my savings due to the false promises given by Anoncoin devs.
Ask yourself this: what's preferable -- a true dev like gnos1s working on zerocoin implementation and not giving updates very often or a slick scammer promoting his twinkle dust instamine scam (50% of total coins)?
Red pill or blue pill?
