Obamas ransom for the Iranian hostages were in currencies other than dollars. Iran is not recognizing dollars. In Iraq. The US has dumped billions in currency, some of which was destroyed intentionally by our own bombs. So for those remaining dollars quickly reaching the value of fast food napkins could they buy bitcoin? Could someone take their cellphone and make a trade for a pallet load of bills? Sure but getting it into a country that still recognizes its value will probably be the hard part. My guess is that bitcoin goes for a lot more dollars there. I had to share that thought for entertainment purposes only.
