Bitcoin was down more than 7% at $39,077.79 at 6:55 a.m. ET on Thursday, according to data from CoinDesk.
On Wednesday, bitcoin surged as high as $42,577 after starting the day trading at around $38,744.

Wednesday’s spike came as optimism around Biden’s executive order on cryptocurrencies mounted. The order focuses on six key areas: consumer protection, financial stability, illicit activity, U.S. competitiveness in the industry, financial inclusion and responsible innovation.
Some high-profile cryptocurrency industry players praised the U.S. government’s move. Cameron Winklevoss, co-founder of the Gemini cryptocurrency exchange, called it a “watershed moment.”
