Imagine if McDonalds came out with a different name? People have associated with that name for their entire lives. Most of us have been here for an extremely long time, and a name change will cause a massive change. People know DRK. You would have to start over marketing wise to get to the point you are at now.
I can see where you are coming from but you have a very narrow view. McDonalds has been around longer than most people's age who are into crypto so you are talking oranges and apples. You cant compare Mcdonalds brand name exposure to Darkcoins. Darkcoins name has been around for like 12 months...this is so young its not funny.....I guarantee you that the majority of hardcore bitcoiners in the main forum still dont know what Darkcoin is and or what it does....
Now compare this to the rest of the world when/if digital currency starts going mainstream in a few years...if you had two options to use as an every day consumer one named digital cash the other darkcoin ...you can guess how much Darkcoin would be utilised....almost zilch...
You want our audience to be a very closed off niche market or be presentable for everyday consumers?
