Get free from Central Powers control by using decentralized currency. The future economy will be totally digital and decentralized. Bitcoin is a worldwide-distributed decentralized peer-to-peer censorship-resistant trustless and permissionless deflationary system/currency (see Blockchain technology) backed by mathematics, open source code, cryptography and the most powerful and secure decentralized computational network on the planet, orders of magnitude more powerful than google and government combined. There is a limit of 21 million bitcoins (divisible in smaller units). "Backed by Government" money is not backed by anything and is infinitely printed at will by Central Banks. Bitcoin is limited and decentralized.
