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 is already big enough and it is different than altcoins, shitcoins that only rely on marketing to shill their shitcoins to investors, create pump and dump games to steal money, bitcoin from cryptocurrency investors.
Bitcoin does not need fund for marketing, promotion and do you think that it is always better to have organic growth?
Bitcoin has its organic growth because it has big developer communities who develop great things for Bitcoin users. If you want to support them, send your bitcoin, satoshis to their donation addresses.
