Perhaps. 

But I believe that the Fed will continue to use it's influence to coerce gubmints to use the dollar.  If/when larger masses of people start using cryptos(and bypass the dollar currencies in favor of Bitcoin/Ethereum/Litecoin/Dash/Steem et al)  then it is possible that gubmint banks could lose their death grip over the masses.

The central banks have one move and we've seen it time after time.  Despite what they tell us, they will increase the supply of money.

Very interesting times... and we all got a front row seat.
