We need to be practical and resourceful at the same time so for me using social media in promoting bitcoin can be the best way in order to inform others and less expensive at the same time.
Keep in mind, that not everyone can trust social media as a promotion to run a project, but depends on those who run it.
Providing information to someone must make them more interested in what they are promoting.
Because everyone always approves a project that runs always leads to fraud. I think this needs to be understood so that they don't always feel disappointed with the project they are running.
