This would really be an addition to increase the demand of Bitcoin and therefore increase the value eventually. I had never seen a commercial about promoting Bitcoin. Although some news already mentioned it and explained it but it would still be better to repeat the Bitcoin commercial every now and then. And time will come there may be a cryptocurrency show that talks about the differenr cryptocurrencies price movement.
We are already dealing with Bitcoin advertising at the Internet level on portals like Facebook, so why would not it be on TV?
In my opinion, it's a good idea. Let the message about Bitcoin spread throughout the world.
Will the government support the advertisement of an unknown thing? I mean, it would be like they are supporting the use of bitcoins. In my country, the government didn't directly agree nor disagreed on the usage of btc instead they only warns people against it.
