OK so the notary would be paid in euros, for the taxes and their fee? However, they then will have no proof of the actual sale price, which is what those fees are based on, how could they verify that. There are lots of rules associated with house sales in France, including the Mairie having the right to purchase if the price is 'right' for them, ie someone selling at too low a price. Laws apply equally to Corsica as to the rest of France. The notaire involved in property sales has to inform the Mairie. Since the euro is the standard currency in France, unlike Bitcoin, the price will be set in euros, so calculating the fees will not be a problem. Bitcoin is simply the unit of account used for this transaction at a given time, the price of the house remains assessed in euro. There is nothing mysterious or dark about it. It's just more convenient for me to pay in Bitcoin, as it could be in any other foreign currency. Frankly I do not understand bit coin, as strange an unreal to me as the Tulip Mania of 17th century Holland and the South Sea Bubble of almost a 100 years later. There's not much to understand about it, although the technical side is fascinating and can be the learning experience of a lifetime. One could simply say that Bitcoin is a currency that exists on the Internet and can be used for a whole range of applications.
