Christine Laggard is in Crypto market, acctualy she has a son who is invested her money..
I think she is not supported Crypto just for media but in private she is supporting and investing a Crypto ....

I don't know if there are two versions of her last name, but if there aren't, you should use what most people know her by. It is true that she has a son who allegedly invested money in cryptocurrencies, but that does not mean that she invests her money. Therefore, this woman has no documented connection to any investment in anything related to Bitcoin.
Besides, she has a very shady past...
On 3 August 2011, a French court ordered an investigation into Lagarde's role in a €403 million arbitration deal in favour of businessman Bernard Tapie. On 20 March 2013, Lagarde's apartment in Paris was raided by French police as part of the investigation. On 24 May 2013, after two days of questioning at the Court of Justice of the Republic (CJR), Lagarde was assigned the status of "assisted witness", meaning that she herself was not under investigation in the affair. According to a press report from June 2013, Lagarde was described by Stéphane Richard, the CEO of France Telecom (a former aide to Lagarde when she was finance minister), who was himself put under formal investigation in the case, as having been fully briefed before approving the arbitration process which benefitted Bernard Tapie.]
In 2013, the press revealed a letter seized by investigators during a search of Christine Lagarde's Paris home, in which she appears to express her full allegiance to former President Nicolas Sarkozy: "Use me for as long as it suits you and suits your action and your casting. (...) If you use me, I need you as a guide and as a support: without a guide, I risk being ineffective, without a support I risk having little credibility. With my immense admiration. Christine L."
Subsequently, in August 2014 the CJR announced that it had formally approved a negligence investigation into Lagarde's role in the arbitration of the Tapie case. On 17 December 2015, the CJR ordered Lagarde to stand trial before it for alleged negligence in handling the Tapie arbitration approval. In December 2016, the court found Lagarde guilty of negligence, but declined to impose a penalty.
