A lot of people make the argument that bitcoin is too unstable to be a currency. I find this completely untrue.
Fiat is actually placed under the illusion of stability, while in reality, it is actually in a constant long term decline due to the debasement of the money supply by the central banks of each country that issues it. Bitcoin has no such problems, as it is decentralised. And even though there may be some short term volatility, it's going to hold its value in the long run.
Bitcoin has PROVEN to be a better currency than the Turkish Lira and the Bolivar. Other countries under a currency crisis will take note that there are few safe havens besides crypto currencies to store wealth. Since other national currencies could see the same fate as these two.
This is a spot on statement. I reckon that in the future, bitcoin will serve as a safe haven for those who want to store their wealth in a form other than a depreciating form of fiat currency, just like what gold is used for rigth now. The countries of Turkey and venezuela are only two of the most recent examples.
