I've read the article and it shows that the majority of the respondents do not own any cryptocurrency, specifically bitcoin and also not interested about buying some anytime soon or later. The reason why bitcoin's adoption has been hitting the critical level of popularity index is because people hasn't even heard of it and barely know what bitcoin is all about, bitcoin is lacking in terms of the marketing that advertise it and make it to the mainstream. The popularity and the good image of bitcoin only circulates within the cryptospace, not reaching non BTC fans and letting them know the things that hooked crypto enthusiast's interests.
        Also, people that are said to be 55 of age above increased the number of non-BTC fans, that article was right that this was probably because people of thatge is nearung the retirement age and would prefer investing in a stable coin rather than bitcoin which is very volatile and risky to even start.
