My guest this week is Preston Byrne. Preston is vocal critic of crazy prices and projects in the world cryptocurrencies. His background is in the legal world and also as a founder and former COO of Monax, which made the first open-source permissioned blockchain client. As Preston says, he is a “blockchain without bitcoin” guy, who believes that this crypto mania will end in some sort of apocalypse for token holders and ICO issuers . We tackle several issues, from his broad skepticism of crypto assets, to the potential regulatory reaction from major governments, to types of coins like stable coins, which Preston views as analogous to perpetual motion machines.  Please enjoy our conversation and for any crypto investors out there, let me know if this conversation affects your opinion of the investing prospects for cryptocurrencies.  Hash Power is presented by Fidelity Investments   For more episodes go to InvestorFieldGuide.com/podcast.
