I'd be curious to see who they surveyed. All I can find is this:
14.4% of Americans seems awfully high to me. I wouldn't be surprised if the results are skewed because the respondents weren't representative of the population. Some demographics will definitely have a higher propensity to use Bitcoin -- Millennials, internet users, etc.
The Profile survey also revealed that Americans holding crypto assets have an average of $5,447 in digital coins
Hmmm, 36.5m x5.447 $= 198 billion, total market cap of all coins is 234 billion, ...Satoshi owns another 10 billion...
Yeah, legit!
These statistics are very skewed and a more accurate survey that has people from all the regions if America, in different age groups and a fair range of internet users would be much more accurate and these previous studies are just estimates...
