Of course it won't be too easy, as the market always gets along with the demand. Publicity is just a way to inform the people that there's an existing digital money that they don't know in a form of cryptocurrency and it's called as bitcoin.
They already know it! Already in 2017 (for a while, which was 2 years ago) it has been hyping over all existing media resources. You must probably live somewhere deep in the woods is you did not hear about digital currencies. It will not work the same again.
At this time people won't buy bitcoin just because they see it once again in some shitty movie.
