This is my entry for the creation of a logo of an international crypto project about advertising and marketing.
The first logo is almost completely black, as most simple icons are always shown, the O looks like a poster or banner (since its an advertising venture) with small colors on it representing data in colors that are commonly related to blockchain and technology.
The shapes on the second one resemble layers or banners, while the symbol on the O makes the statement that it relates to blockchain. Warm orange colors are often used in advertising while teals are used in technology and crypto.
