Berkshire Hathaway’s Warren Buffett said on Wednesday he will never invest in cryptocurrencies.

“I can say almost with certainty that cryptocurrencies will come to a bad end,” Buffett told CNBC in an interview.

Buffett’s comments come a day after JPMorgan Chase Chief Executive Jamie Dimon said he regrets calling bitcoin a fraud, referring to comments he made at a banking conference in September.

Bitcoin has taken the investing world by storm, surging to a high of more than $19,000 and created a divide on Wall Street about whether it is a legitimate financial instrument.

Bitcoin was down around 3 percent at $13,981.53.
