Buying (and Holding) Crypto currencies is a great way to hedge against inflation.  For example, in 2010 10,000 Bitcoins were used to purchase a single Papa John's Pizza.  Those same 10,000 Bitcoins (had the owner held onto them) could be used to purchase an actual Papa John's franchise.  You see, in 2010 10,000 BitCoins were worth about $30.  Today (October 2017), a SINGLE Bitcoin is worth over $5,000 (or $50 Million for 10,000 Bitcoins).  That was one expensive pizza!
