John McAfee on Wednesday challenged JPMorgan CEO Jamie Dimon's skepticism of bitcoin.

Dimon on Tuesday called bitcoin a "fraud" that will eventually blow up. McAfee, whose company MGT Capital Investments mines the cryptocurrency, said he respects Dimon and people in his position "are not idiots," but he challenged Dimon's criticism.
