This news is indeed both a shock and excitement, especially to Cryptocurrency users. I think French's government really underwent through a thorough study and investigation on Cryptocurrency's advantages and disadvantages. It is a good thing they are very brave to experiment if Cryptocurrency will be effective. Though it is decentralized, and the first article mentioned that France will ban Bitcoin because it can be used to shift taxes and for money laundering activities.
And because of this adoption, French students are taught just as mentioned in the third article. I think this is very helpful since young generation are more critical thinkers and who knows, maybe one of them could lead to Cryptocurrency's success if ever, in the near future.
Overall, I hope that this would be the start of an open-minded community. However, the cons is that it might spark money related acts punishable by law. And that discipline might be hard to instill among people.
