Federal Reserve Governor Christopher Waller on Friday had a pair of warnings for those involved in cryptocurrency assets, telling buyers they could lose their investments, and banks that they must guard against bad actors and risks to the financial system. Speaking at the same conference several hours later, Philadelphia Fed President Patrick Harker presented survey data suggesting that despite those risks, cryptocurrency will likely remain in demand. In recent months the cryptocurrency industry has been roiled by massive losses for investors, bankruptcies of crypto exchanges, lenders and payment platforms, and high-profile court cases including a criminal case against FTX founder Sam Bankman-Fried.
