Like a documentary movie?
Pros:
- Access to a large population;
- Visual presentation and clear direct message to the audience;
Cons:
- Bitcoin documentary movie often contains a lot of politically sensitive information;
- I'm not sure that the general public is ready to digest/accept the philosophy behind bitcoin;
I think advertising it on national television can be a good thing because it gives popularity and surely happened once it was on aired many people would decide or interest to try bitcoin because they already have a knowledge how to enter into cryptocurrencies.
