Why not store the money in Bitcoin instead? It's outside of government control and you should get a nice return on your investment.
The price you can sell an asset for is whatever someone is willing to pay, on that day. If sentiment turns and everyone is selling bitcoin, the price will most definitely not be going up.
Bitcoin isn't liquid enough for me to trust it for emergencies. If I needed to pay for a hotel or a plane ticket, the process of translating that to cash, then a pre-paid VISA card is way to complicated and probably expensive.
