Advertising in any case will help bitcoin become more popular. But most people who knew nothing about bitcoin and how it works, see this as a Scam. Now a lot of people who even know anything about bitcoin, think that is a bubble. In General, the more people know and are interested in this, the higher the price and the demand will be bitcoin. But TV is now every year becoming less popular. I think does not make sense to advertise bitcoin on TV, when we have such a platform as internet.
