Bitcoin is the most popular currency that no one can take from you (as in Greece), that you can carry in your mind (brain wallets), that is deflationary instead of inflationary. It is censorship-resistant currency. Bitcoin weighs nothing. Unlike other currency, it is not subject to the whims and monetary policy of a government regime. Fiat can be taken, transfers blocked, accounts closed, administratively lost. Bitcoin is the "World Wide Ledger" for the World Wide Web. Take a look at Monero for the best tool for the anonymity use-case.
