I am agree with your statement that television plays a key role in eldery people's choices. Lots of them still do not understand that TV is just a huge mechanism of manipulations. Sometimes even in case people among elders use computers, Internet and even online means for payments or so, they still used to believe to the news and statements of government representatives. But I saw and met among elder people lots of who are very deeply involved into crypto world and even always hold their finger on the pulse on the new directions in crypto like DeFi, different new projects and so on. In my opinion it is better to choose people who are active in life in general. Because those elder people who prefer stating at home and watching TV, live only for payments from the government, they will not be ready to leave their comfortable armchairs and to accept changes even with some perspectives. It would be easier to explain the topic of Bitcoin and crypto, because active people in life in general are more open to the new views and information, they are not afraid of trying something new and to change something in their usual life. And first of course - it is better to show them new opportunities that may appear in their lives in case of using crypto and Blockchain.
TV ads about Bitcoin could greatly induce the elderly into knowing more about it. However, such efforts could be in vain as most seniors aren't into the latest technological breakthroughs. All the "technical jargon" surrounding crypto/Blockchain tech, makes everything look complicated especially to non-tech savvy people. The elderly are better off using physical cash for daily payments, as it won't be going anywhere soon. It might take decades before the world's economy fully transitions into a cashless one. While we're in the "transition phase", physical cash will still be a relevant payment method. I'd expect the elderly choosing physical cash over Bitcoin because of its easier learning curve and price stability. Only a small minority will use Bitcoin as an alternative financial system for their own benefit.
All in all, young people will be the ones that will adopt Bitcoin to a full extent. It's evident that old people are reluctant to change. They're accustomed to the traditional way of making payments via the legacy financial system. While it's not that hard to make the elderly understand how Bitcoin works and how to use it, most of them will continue living with Fiat. There are many educational materials available on the web right now that you can use to carefully guide old people into the "crypto revolution". In all ends, the decision of joining Bitcoin will ultimately lie on the person himself. Just my opinion
That is actually a great idea BUT placing it on public advertisements means that it won't just be introduced to the elderly. It would also present Bitcoin as an usable Currency that people can gain money from. It would go through lots of processes before making it into an advertisement since networks won't advertise what they do not understand. It would still be a good idea to just show results and outputs from what can we benefit from Cryptocurrencies. In that way, people who are only interested would be entice to ask necessary questions.
Are there any TV ads as of now about bitcoin? Cause I think ads about this technology are only available online and in the internet, example are youtube ads, blogs, and social media ads. Never seen one on a TV because of the cost maybe of an ad per 30 sec on TV. And also maybe because our country doesn't even care about the existence of bitcoin, and its kinda weird to see one about it on TV tho.
One problem also is how would you create an ad for bitcoin that will not look like a scam, cause you already know by now that bitcoin has this image of being used as a scam and for illegal activities. There are also a lot of spammers in the the internet posting copy paste bs about bitcoin. The ad should look professional and interesting. That's really a problem for all products but somehow there's something making it harder for bitcoin to be trusted.
The only thing I desire for bitcoin is to be adapted by the government so elderly can acknowledge the potential of bitcoin in our society. As of now, bitcoin is threated as a scam asset because of this people who're creating scam and ponzi that involves bitcoin to their greediness.
