Cryptos are decentralised Ponzi schemes: JPMorgan CEO

JPMorgan Chase CEO Jamie Dimon in a congressional testimony in US on Wednesday criticised cryptocurrencies and said they're "dangerous". "I'm a major skeptic on crypto tokens," he stated, adding, "They're decentralised Ponzi schemes, and the notion that's good for anybody is unbelievable." Dimon was speaking at a meeting of a committee that is working on a bill to regulate stablecoins.
