Another interesting data point. When I look at the transaction ID for the "pickpocketed" transaction, I see:
https://blockchain.info/tx/e00709e118af2b1d6737ccaf10c8423d6a49b24b72472f2754d35efca7b0ab23The page states: "Warning! this transaction is a double spend of 112743537. You should be extremely careful when trusting any transactions to/from this sender."
The imported address I used to send the BTC was deterministically generated on brainwallet.org using a not-so-strong passphrase (after all, this is just a test). Is it possible that someone else in the vast Bitcoin universe used the exact same not-so-strong passphrase and just got an unexpected donation of 0.01 BTC?
I'm more concerned about the mystery than the $$$. If I learn something today, the lesson will be worth the $6 USD.
Thanks (again).
