Here is the line that caught my attention: "St. Louis Fed President James Bullard admitted to Reuters in a recent interview what the real concern was: '(We could) wake up one day and most of the big banks have been eviscerated and most of that activity has moved elsewhere.'"
I tracked that that claim back to the Reuters article Bubble or breakthrough? Bitcoin keeps central bankers on edge by Francesco Canepa.
Canepa made the same statement but did not provide a link.
Business Insider Interview
On October 13, Business Insider interviewed Bullard. BI reported The rise of a new kind of finance is setting off alarm bells at the Fed.
