But he reiterated his view that blockchain, the record-keeping technology behind Bitcoin, is "real." He said that initial coin offerings - a form of cryptocurrency fundraising used by many blockchain startups - had to be looked at "individually."
Dimon in recent months has compared Bitcoin to the Dutch tulip craze in the 1600s, said he would fire any JPMorgan trader caught dealing in the cryptocurrency, and predicted it was bound to implode. He also has said an unregulated currency's prospects for survival are essentially zero, as governments would be unlikely to tolerate one.
"Bitcoin to me was always what the governments are gonna feel about Bitcoin as it gets really big," he told Fox Business, "and I just have a different opinion than other people."
