In 1929 if the shoeshine guy was giving you stock tips, it signaled a very different level of market euphoria than today when your gym trainer is talking about stocks.
Also, today we live in a world where there's just so much more accessibility to information. Only about 1.3% of the planet has ever owned Bitcoin. About 13% of Americans have ever owned Bitcoin but 90% of Americans surveyed have heard of Bitcoin.
I don't mean this to be about Bitcoin, only trying to point out the massive gap between something that is relatively niche, and the number of news articles/stories, discussion, etc about it.
>With one study suggesting ~25 million cryptocurrency traders outside the USA & Europe, it seems quite likely there are over 100 million owners of bitcoins.
>If true, it means about 1.3% of the world's population owns bitcoin.
I've seen a few other sources make a similar estimate using different methodologies.
