thanks for sharing...
what got my attention in the overview was in 2010, when A programmer named Laszlo Hanyecz, who lived in Florida pays 10,000 Bitcoins on a pizza, that was originally bought from Papa Johns by a volunteer in England. The exchange rate at the time put the purchase price for the pizza at 25USD. comparing the exchange rate between 2010 and now, we can see bitcoin has come to rule the global currencies.
I think we're quite a bit off bitcoin "ruling" the global currencies. But it is certainly interesting that such a simple idea could have such an impact on the way we treat money and the way we treat true ownership rather than relying on a 3rd party for everything
