Contentos is a decentralized content ecosystem which awards users for uploading videos, photos and other material
Contentos got listed on Binance dex few weeks ago and got listed on Binance on Aug 3 which is not a surprise since one of the investors of the project is none other then Binance Labs. Contentos didnt have any IEO/ICO or public sale.
Contentos has several ways for users to earn COS: sign up every day, open free chests and play treasure hunt on COS.TV or use photogrid and get paid for content you upload ;)

Price upon listing on Binance dropped almost 50% in 3 days but yesterday it jumped by almost 250% with a LOT of volume increase.
Since the project has a lot of potential and Binance Labs is an investor i expect it to have a really good future. Especially since not a lot of people heard about it so once people get to know it it could make some serious gains.
