On January 29, 2014, he provided risk testimony before the New York State Department of Financial Services hearing on virtual currencies. In this testimony[clarification needed], he stated "to transform Bitcoin into a virtual currency would require regulation, centralization, creation of a legal framework and strong regulatory oversight." He raised concerns about Bitcoin, including lack of consumer protection, it being a high-risk virtual commodity, having an artificially inflated price, extreme hoarding, hyped demand, high potential for market manipulation, and fraud. On April 2, 2014, Williams provided congressional testimony before the U.S. House of Representatives Committee on Small Business discussing the 10 major risks associated with Bitcoin. In 2013, after Bitcoin peaked at $1,200, Williams predicted that it was in a bubble and would trade for less than 10 dollars by mid-2014. In 2014, Bitcoin prices dropped by over 50% but bottomed out above $200 through 2014 and didn't reached $10 like he predicted. Other academics including Yale economist Robert Shiller also consider Bitcoin a speculative bubble. In January 2018, he further cautioned investors about the cryptocurrency hyper asset bubble, stating it is fraught with uncertainty and high risk. Prices can also be manipulated, and exchanges that trade them tend to have little to no regulation and consumer protections.
