The dollar is not backed by the US Military unless you justify the U.S. bombing countries into oblivion unless they forced to use the dollar to trade for commodities like oil. Nor is th Dollar backed by US citizens other than their belief the the dollar is money which belief was created by the banks and the willingness of people to work for the dollar in order to pay pack debt in the belief it is money. The dollar is backed by DEBT which is worse then nothing. Crypto currencies are issued in limited amounts to keep them rare like gold and sliver and there is NO INTEREST ATTACHED when crypto currencies are created, unlike the fiat currency. So you have been mislead or do not have a firm understanding of the issues.
