This question has been raised several times, and I have noticed that some people conclude that the lack of adoption is due to people not understanding Bitcoin or seeing it as a scam.
But I don't think the world still views Bitcoin as a bad thing today, though I know a lot of you thought that, but it is not the case.
I feel the reason for the low rate of adoption is just because people think it's not for them. Bitcoin has been around for over a decade, and any thought that most people would have had about it being a scam must have faded by now.
But at the same time, if you look at it, Bitcoin is a risky business; if you invest money, there are two possibilities: it will either yield profits or losses. Many people today are not fans of investment, not to mention buying assets that heavily fluctuate in price. They would choose to save money earned from hard work, and a few might invest in low-risk markets, even though inflation is still eating them up.
So it would be hard for them to consider holding Bitcoin to use it daily.
Nevertheless, the community is still growing bigger 💗, and people's interest in Bitcoin and cryptocurrency keeps growing.
You mistake the change of a couple people's minds as a representative of the collective opinion of the people regarding bitcoin. A good portion of the critics still see it as a ponzi scheme, and well, of course there's a good portion of the population still quite ignorant about bitcoin's utilities and its benefits.
I would not say the world sees it as a scam and neither would I say that it is a lack of interest but rather, I would say many people who have heard about bitcoin and are not indicating interest are just sceptical about it maybe due to their experience in the past with Ponzi, scams etc which made them to not put much interest but observing as events unfold it self.
I believe we all know that advertising is a key tool in getting a commodity to the consumers. If bitcoin is properly advertised im the sense that people are taught or told about bitcoin, I believe that Idea of seeing it as a scam would be dropped and people tend to take part in such activities when they see someone close or related to them doing it. That arouses their interest to learning and knowing more about it.
You just debunked your own argument. The people are skeptical of bitcoin's legitimacy? Well because they still think it's a scam. There's just no other reason behind it.
Advertising bitcoin isn't enough. Proper education as well as word of mouth is what's going to expedite this adoption, nothing else. The more you artificially swoon people to choose bitcoin, the more they'd see it as a scam.
