BitFinex’s transaction prompted @Rhythmtrader to praise the “true power of bitcoin” that no bank could match.
Only newbies are astonished by big transactions and their small amount of fees, anyone who has at least basic understanding of Bitcoin knows that there's absolutely no difference how many coins you move, so there's nothing spectacular about such transactions.
As for "power that no bank could match", banks don't charge any huge fees on people who move billions, and such large transactions do happen frequently - large companies get bought, countries do transactions between each other, billionaires make donations and so on.
If the coins were of unknown origin, it could have been a issue of debate. This one is not. Exchanges do fill and distribute address with a large amount often. If you keep on looking at the 100 address with highest balances, many of them keeps changing everyday as the exchange keeps moving the coins.
