That volatility has led some financial experts to call crypto a speculative asset. Financial advisors generally recommend crypto investors only allocate a small portion of their portfolio to it.”Potential investors are leery of investing their retirement savings into what has been, to date, a fairly volatile investment,” said Mark Lush, who manages the Behavioral and Economic Analysis and Decision-Making team at NORC.

“Cryptocurrencies may have staying power as an investment option, but our hunch is that they will continue to lag behind more traditional investment opportunities for the foreseeable future,” he said.

Just 11% of those not investing in cryptocurrency said they were extremely or somewhat likely to begin trading in the next 12 months, the survey found.

Crypto investors tended to be younger, and more diverse in terms of gender and race and ethnicity, relative to retail stock investors, according to the survey.

The average crypto investor is 38 years old, whereas stock investors are 47.

Forty-one percent of women, 44% of investors of color and 35% of those with income below $60,000 a year traded cryptocurrency in the past year — higher respective shares than the 38%, 35% and 27% who traded stock.

However, investors with college degrees tended to favor stock — 51% traded stock in the past year versus 45% for crypto.

The University of Chicago survey polled a nationally representative sample of 1,004 American adults from June 24 to 28.
