My idea for a logo, or for the bumper sticker (I'll work on it) is....One of the current logos look a trademark infringement on the Mets logo (and the lettering....cheap). I was picturing an "NY" surrounded by a large gold "C", followed by lower case "ion".

On the bumper sticker maybe underneath could say, "The coin that never sleeps".

Also....I could make it one of those foil things that change depending on the angle you look at it. The "C" and "ion" could be gold that gleams when the angle changes and a small diamond topping the "i" that sparkles.

In other words, when the angle changes you'd just see the word "Coin" in shiny gold foil letters, with the diamond sparkling above the "i". Making it obvious and stand out that it's cryptocurrency.
