I do think the value in all these currencies is that it will change the value Banks in general bring to society.

If we see a widely traded and daily useful crypto-currency in use for general goods and services, we'll see a deleveraging of the banking system.

Right now how often do you exchange a real Dollar or Nickel for goods or services. Chances are your token of exchange is your credit or debit card, with a balance maintained by a bank.

Would be very interesting to imagine the world we will live in if the banks are no longer keeping the ledger for society.
