Calling an alt coin "Greececoin" is a dead giveaway to Greeks that it is anything but Greek
To say "Greek Coin" in Greek actually rolls off the tongue with a nice ring to it. (Ελληνι-coin;) Greeks don't call Greece "Greece", this is an English word for their country.
I can confirm that "Greece" is not how we Greeks call our country. "Greece" is mostly used in other countries. We use Hellas instead (Ελλάδα). "Greek" a nickname Romans gave to us but it was kept and used by the rest of the world after the adaptation of the Latin language to Europe.
But nevertheless, I don't think people here care about historical correctness.
