If you were thinking of Christine Lagarde then you should know that she is the President of the ECB (European Central Bank) and that her only influence on cryptocurrencies is mainly to talk about them in a very negative context. There may be another woman with the same name and similar last name, but I didn't find her.

I don’t want to explore the background of every person you mentioned, but I’m sure a lot of them didn’t start from scratch, and that some had very wealthy parents who helped them be what they are today.
