Today I was amazed at how low the commission was when transferring 0.07 bitcoins. Only 192 sat !!! The transfer took about 10-20 seconds. It's very, very cool. About $ 650 for $ 0.017 - this is something! Bitcoin is the future!
Probably you were just lucky, because generally transactions with such low fees take much more time to be processed.
Though I can remember somebody showed a screenshot of transaction where 45k btc were sent for 4 dollars only - yeah, that was really amazing.
