Somehow, I doubt that even 50 million US residents own cryptocurrencies, but even if that is true, how many of them actually own Bitcoin, and how many of them are "gambling" with various altcoins? I personally think that this figure is overblown for the reason that everything has to be big in the US, so why not the number of users of cryptocurrencies - and someone is obviously using these numbers very well to create FOMO "Hey, 50 million have already invested, what are you waiting for?"
Yes, your words make sense, the numbers that I read about the crypto community in the United States do not talk about those who own Bitcoin specifically, but about everyone who owns any altcoin or maybe even those who bought shares of ETF companies, all of these will be counted, although this is wrong because the owners of shares are not considered part of the crypto community.

What I know is that before the methodology of such research was that a company would conduct a survey on 1000 or 2000 people, asking them if they owned cryptocurrencies, and if 10% gave a positive answer, then they would conclude that they could map that percentage to the national level. Of course, they all talk about a statistical error that is between 2-3% and that is not too questionable, but if you do such a survey on people who work in IT sectors, large technology companies and the like, then you are targeting people who are much closer to such investments than someone who works in a fish processing factory or is an ordinary farmer.
To be honest, they don't do it only in the US, we have
"crazy" data on the number of crypto users from various parts of the world, especially India or some African countries, which when studied in a little more detail do not make any sense.
