"Knowing 85% of Millennial women do not invest, he was impressed to hear Stash has a 60/40 male/female split."

I find the 85% number quite interesting. Maybe women don't find risk taking appealing in any way?

"The fact so many are participating in the cryptocurrency craze is the best evidence they are risk-seeking."

I would argue that many of them have no choice but to invest. Nobody wants to work at Starbucks to pay off those ridiculous student loans.
