For me, it's more like of a box of crayons because describing it as chocolate can be obvious enough to have sweet content which everybody likes. For box of crayons, you'll never know what color you would have inside and you must accept the color of the crayon even if it's not your favorite one. As to ICO, you'll never know what will be the outcome because it might fail midway in the project or you will just learned that it's a scam after the ICO ends.
