If you have a crisis you need some safety not gambling on a experimental currency who have lost value the last two years.
Bitcoin dont lose its value, but its price just decreased.
Unlike real currencies it looses value when the price goes down. If $ goes down 3% tomorrow there will be no difference in the price you pay for stuff but if
BTC goes down the price for stuff goes up. That is because it is 100% linked to dollar and does not have a value on its own.
Many nations want their currency to get lower exchange rates because it is easier to sell their goods to other nations. Only nations who import a lot of stuff want a high exchange rate. Bitcoin has realy nothing to do with trading and it has its whole value based on current exchange rate.
