When I read what Christine Lagarde said, I found it interesting, but with all due respect I don't agree in some point, mainly with the fact that central bank and government must continue to monopoly money supply and regulation. It's was not possible with Internet(web 2.0) and it will not be the case with blockchain and cryptoTech (3.0). I know that she is trying to manage her position and protect her salary then also appears good with her cartels member friands.
However, what we are going through right now has never been before: the "Internet of money" control and autoregulate by blockchain algorithm, as the famous professor of Harvard law school Lawrence Lessig said more than 10 years ago : "Code is law" it's definitely true, no one can't stop it. goverment and
central Bank will still be there for long time but they must reinvent radically their mission or die.
