I'm just reading an article in the newspaper. Klaus W. Wellershoff (a last chief in UBS Bank) says that's impossible to use a currency with volatility as money. If the value of the money decrease, that means the value of the merchandise decrease. For example : if you buy a flat with bitcoin and few years later the bitcoin value decrease... Your flat lose his value as well.
What do you think about this argument?
You just gave an unfortunate example. If the bitcoin rate falls, the apartment bought for bitcoin decreases in price in comparison with bitcoin, however it will retain its value in comparison with other currencies.
I can give another example. There was information that in December last year, Russia and Turkey had the first deal in bitcoin. Russia supplied Turkey some goods, it seems, some products. This deal, of course, was prepared in advance and in the agreement, a certain number of bitcoins was delivered according to its rate for that time. In December, the bitcoin rate rose sharply, we will count twice. This means that Turkey actually paid twice as much money in bitcoin. Then the bitcoin rate fell from almost $ 20,000 to $ 6,500. How can economists calculate the price and the amount of the goods in this case? Will Russia and Turkey want to play this roulette next time? Very much I doubt.
In the end, we can say that, in fact, decentralized crypto currency can not be used as money, but as the main currency. Such a crypto currency can quite successfully go and be used as money and only along with the circulation of ordinary money.
