Which exchanges BASE will be traded on?

can anybody tell me what does it means?

this is what they explain in their website
'Participation and interaction with other users in our platform will require usage of our Ethereum-based ERC20 token CryptoAds.

Advertisers create ad content and media resources to be offered to their target audiences. In exchange for ad space, the Advertisers offer payment in the form of tokens to Publishers. The Advertisers can specify where and how their ads should be delivered, and how much they are willing to pay.

Publishers agree to display the content produced by the Advertisers on their websites in exchange for token payments. The Publishers can specify criteria for advertisements that they are willing to display, including rates per click and per impression, ad type and genre, price range, duration of display time, etc.'

what are the benefits to use your platform and not any other one?

Autobay allows you to buy, sell and auction new and used cars from private sellers and dealerships from all over the world in the largest blockchain based e-commerce environment.  You will be able to pay with cryptocurrencies for the car you want with low transaction rates and with the security of a cash free payment process.
