 For example, misuse of initial coin offerings, or "ICOs," on the Ethereum blockchain platform have been one such method, known as ""smart Ponzis"" per the "Financial Times".The novelty of ICOs means that there is currently a lack of regulatory clarity on the classification of these financial devices, allowing scammers wide leeway to develop Ponzi schemes using these assets.Economic bubbles are also similar to a Ponzi scheme in that one participant gets paid by contributions from a subsequent participant until inevitable collapse.
