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.
Bitcoin does not need funds to promote itself - it has been promoted for free so far. Many centralized platforms utilize bitcoin to attract their customers - so I don't think bitcoin needs to pay much for such promotions. You should realize that because you've been here since 2017 - but your question doesn't make sense.
