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?
It's a pretty much biased and ridiculous point of view. Real property value won't decrease due to cryptocurrency price falling. Cryptocurrency is only an instrument of exchange not a value itself.
