I kind of agree. It feels so basic in colours and boring, i think it should look better with a more metallic look, as a real coin. The design around the coin should be removed and perhaps placed inside the coin itself as an outer line.
Maybe we should have a logo contest and raise a bounty? Start a new thread for that perhaps?
Personally, I prefer a flat design. It is a crypto-currency after all so it should look different from a real coin. Just my 2 cents though.
The current logo rocks! Blew me away when AC was resurrected and was the first sign AC was going to survive. So yeah, it has some sentimental value for me as well.
