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.
