As a result, about 36.5 million Americans own some form of crypto asset.
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!
Good catch. Some respondents obviously overstated their holdings.

I also heard that Milennials are also more likely to think positively about Bitcoin than boomers. This should make adoption go through the roof at the next recession.
They are, but I'm not convinced that'll improve Bitcoin's prospects during a recession. Millennials are largely the people buying bitcoins. When they're losing their jobs because of the recession and can't pay their rent, what are they going to do -- buy more bitcoins? No, they'll probably be net sellers instead.
