That's interesting! You made me read more about Bitcoin transaction fees (I found this http://bitcoinfees.com/ offering an explanation, although I can't appreciate its quality in this regard). I found this disturbing: "If any of the outputs (including any change) of your transaction are less than 0.01 XBT, then a fee of 0.0001 XBT is required."

Bitcoin is fungible up to a "Satoshi" fraction, yet the low-amount transactions are discouraged. Actually I'm not sure how it would be even possible to operate with amounts of 0.0001 Bitcoin or lower in the current condition (and that's one US Dollar at 10k USD/Bitcoin)!
