Just by trying to change their mind and vision about Bitcoin, maybe that would be a good start for starting to make all this thing possible, but being serious, i think that it can take a long time to convince everyone in here
Its difficult to convince them, they will believe us if we show them proof, because there is a saying that to see is to believe. For me, i think we should let them be, let them see for themselves, because if they see you that you're successful, im sure that they will invest on it too. Wise investors will always seek for the reliable source, they are not easily deceived by the news spreading.
