Is there some group which collects funds for Bitcoin promotion? If some group like this can create advertisements for Bitcoin, more people can become aware. Such mediums should be targeted which have reach on audience that is still not familiar with crypto.
Such group might exit, but I have never come in contact with anyone. But it is common to see crypto exchanges and other service providers include Bitcoin in their promotional activities. Most advertisements will always include the Bitcoin logo or name on their websites and social media platforms bitcoin is the most important cryptocurrency that will always be mentioned if you are discussing or dealing on cryptos.
It is also common to see presidents discuss Bitcoin and two nations have adopted Bitcoin as legal tender, El Salvador is standing with Bitcoin while sadly Central African Republic has repelled the law. The president of El Salvador Nayid Bukele has been steadfast regardless of the challenges and attacks he is facing from global actors. Presidential aspirants in the US and Argentina have also included bitcoin policies in their manifestos making it popular in the country.
There are also top business executives like Michael J. Saylor the Former CEO of MicroStrategy who are die-hard supporters of Bitcoin. They openly speak well about which also promotes Bitcoin.
Other genuine social media influencers have done a good job in promoting Bitcoin such as Andreas M. Antonopoulos. We also have reliable websites such as bitcointalk.org that give free Bitcoin educational services to the public. Don't forget that reputable members of the forum freely give information about the Bitcoin space, this is also a promotional endeavor. It is common to see people ask questions and receive quality answers from this forum. Individual members of the forum also engage in Bitcoin promotion, there are posts in the forum where members engage in awareness programs in their location.
