There are a few reasons there is no marketing for BTC, first of all Btc is not a company and therefore there is no team or head for marketing purposes, also Btc is not ready for marketing and it will not be allowed by governments because Btc is a threat to them as of now.
On top of that Bitcoin is also not ready for being adopted due to various reasons, you can think of transaction fees, speed, etc. however the future in my oppinion is bright for Btc, each day Bitcoin is not dead is a day closer to adoption.
