FinansStephen Diehl: Crypto is the «commoditisation of populist anger, gambling and crime»«Cryptocurrency is a giant scam, although a complicated scam … » So begins Stephen Diehl’s diatribe against the crypto industry.Stephen Diehl’s book, «Popping the Crypto Bubble», traces Bitcoin’s emergence during the global financial crisis to the post-2016 crypto gold rush, which he refers to as the «Grifter Era». He argues that crypto is slow and unreliable. It cannot be both a great investment, which goes up and up, and a viable currency, which offers stable value. He argues that crypto assets’ price is based largely on there being an even greater fool who believes the hype.Foto: Armend Nimani/AFP/NTBHenry Mance (FT)
