Personally I see the coin image as something that can coexist with a darkcoin logo, I see them as different things. But that's just my 2c, and doesn't count as any official viewpoint. From reading this thread, it's clear that using the coin as an official logo is a divisive issue, so the idea with that bounty is to produce some options and have the community vote for which they like best. If the community votes to keep the existing logo, that's fine. Or someone might come up with something that blows everything out of the water -- we just don't know yet.
