Well, it seems that not only France, but any government, institution, media, corporation, declared war on the cryptocurrencies.
Two explanations:
1) they are scared and try to destroy cryptomarket
2) the want to profit, so they manipulate the market to make price fall to buy cheap.
We'll see.
Still some countries within the SEPA zone are not willing to agree with France and Germany about these over-the-top regulations: let's see how the G20 summit goes, but UK, Ireland, Cyprus, Malta all share a different vision. There won't be a consensus we can be sure about that. Too much money involved.
