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 is absolutely true and that's why economists have argued that bitcoin should be a common currency. Strong volatility is not eligible to make a common currency. because when its prices fluctuate, people don't know how much money or revenue they have each month to plan for the future and everything will get messy.
