yes it is a good idea to develop bitcoin widely so that bitcoin get fame, but doing this is not easy. If bitcoin is advertised on tv then everyone in the world will know bitcoin
actually good but what we want to advertise by can benefit from advertisement? maybe for this ico program is very good to be able to boost their sales
Technically, if there would be some advertisements made about bitcoin, we will benefit a lot from it. Imagine if people got a sudden interest in bitcoin after watching the advertisement, they will invest in bitcoin and there will be more users of it resulting in a price increase and there will be more merchants that will accept bitcoin.
