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.
Am aware of nothing not unless you are looking for scammers that will pretend to be good Samaritan but will only take the funds and run away.
actually we can help the advertisement on our own without asking anyone , just have them on a social media but of course not your main account so will not be exposed to scammers and hackers.
what I mean is that there are parameters we can use to help gaining audience and that is what we have to do.
don't let others collect funds for this just use yours.
