Jamie Dimon speaking at the 2017 Delivering Alpha conference in New York on Sept. 12, 2017.

J.P. Morgan Chase Chairman and CEO Jamie Dimon is backpedaling a bit on his earlier criticisms on cryptocurrencies.



In September, Dimon called bitcoin a fraud. "I regret making" that comment, he said Tuesday on Fox Business.

"The blockchain is real," Dimon added in the interview. "You can have cryptodollars in yen and stuff like that. ICOs ... you got to look at every one individually. The bitcoin was always to me what the governments are going to feel about bitcoin when it gets really big. And I just have a different opinion than other people."

ICOs stands for initial coin offerings, a controversial way some cyrptocurrency companies are raising funds.

"I'm not interested that much in the subject at all," Dimon added in the interview.
