\"There\'s no such thing as bad publicity\" is a phrase that\'s often attributed to showman P. T. Barnum, but is probably apocryphal. Oscar Wilde did say that \"The only thing worse than being talked about is not being talked about,\"and for Bitcoin, even talking trash has helped fuel the flames of public controversy.

With Blockchain technology and digital currency trading rattling the cages of even the most conservative banking institutions, Jamie Dimon\'s claim on September 12th that Bitcoin was a \"fraud\" certainly made cryptocurrencies a major talking point. Dimon is the CEO of America’s largest bank, JPMorgan Chase, and his remarks are therefore widely reported and frequently influential, even if they rebound in quite the wrong direction.

A financial bruiser with a track record of supporting the policies of the 1%, Dimon continued to denigrate bitcoin in subsequent public appearances, and to badmouth opponents of the central banking system. On September 22nd, he was reported as saying that bitcoin was a novelty, worth nothing, and that governments would eventually shut down digital currencies if they got too big. On the other hand, he intimated that Blockchain tech itself was a valuable innovation, digital currencies notwithstanding.

If there\'s anything guaranteed to get crypto investors going, it’s being slagged off by the establishment, and Dimon has so far done a fine job.
