Bitcoin jumped 10% to a record high on Thursday, breaking through the $5,000 barrier, while a top JPMorgan Chase ( JPM ) executive signaled openness to cryptocurrencies despite a hard line on Bitcoin from CEO Jamie Dimon.

[ibd-display-video id=2354661 width=50 float=left autostart=true] The price of the digital currency stood at $5,313.67 in late-afternoon, according to CoinDesk . Just a few weeks ago, it was hovering around $3,000 amid regulatory crackdowns in China and South Korea, along with mixed assessments from some top U.S. financial executives.

While Dimon has called bitcoin "a fraud," JPMorgan CFO Marianne Lake on Thursday said the bank remained "very open-minded" to digital currencies that were properly regulated.

Her remarks came during the bank's Q3 earnings call with reporters, in response to a question about whether other financial firms' potential advances into digital currencies were a mistake.

Dimon, on that call, appeared uninterested in offering any more extended riffs on Bitcoin's fate. Other Wall Street chiefs have been more flexible lately.

Morgan Stanley ( MS ) CEO James Gorman said at a Wall Street Journal event last month that digital currencies were "more than just a fad," according to CNBC. Goldman Sachs ( GS ) CEO Lloyd Blankfein tweeted last week that he had yet to come to a conclusion on the currency.

"Still thinking about #Bitcoin," he said. "No conclusion - not endorsing/rejecting. Know that folks also were skeptical when paper money displaced gold."

The Wall Street Journal also reported this month that Goldman Sachs was considering whether to develop a Bitcoin trading operation of some kind.

IBD'S TAKE:Even as some economists and executives digest what Bitcoin means, the man known as " Bitcoin Jesus " has fewer doubts.

JPMorgan closed down 0.9% at 95.99 in the stock market today, still within range of a 95.32 buy point of a flat base, after reporting Q3 results. Goldman eased 1.1%, while Morgan Stanley lost 1.2%, finishing right on its 48.59 entry from a cup-with-handle base .

Nvidia ( NVDA ) and AMD ( AMD ), whose graphics cards are often used to process digital-currency transactions, rose 0.1% and 2.3%, respectively.
