It will be pretty bad.. Thats a fact.
The economic part of it will be the smallest problem.. The consequences are the dangerous ones .. Like food logistic if it shuts down even a week .. And we were CLOSE 2008, and if The Fed steps in this time.. Its over for the dollar.. And that will start an even more dangerous avalanche..
Im a simple guy.. I keep all my saving in Silver (and gold) phyzz.. Several location, none in a bank, and a few BTC for survival .. Than i pray i will not be a total shutdown.. Because then we will have gangs on the streets after a few days toking for .... Everything ... Gangs of ruthless so-called humans.
