CNBC's Jim Cramer said Thursday he's unsettled by the idea that highly volatile cryptocurrencies appear to be influencing trading in the U.S. stock market.
The Dow Jones Industrial Average, the S&P 500 and the tech-heavy Nasdaq were all higher early Thursday as bitcoin and other cryptos recovered. Bitcoin later came off its highs after the Treasury Department announced its support for more strict regulation on cryptocurrency transactions.
With the intraday improvement in stocks on Wednesday likely tied to the afternoon bounce in the crypto market, Cramer said, "It's insane. It's insane."
