Dear Bitcointalk Team, in fact, I have been stolen of 0.04 btc and here is the transaction:
7ccd211dc0dc0d62b21df7ef439678dffd43d1890915357466a2dbb4070992b9
although I didn't send any bitcoin from my wallet, how this happens?
and how I protect my wallet from stealers?
please help me to reverse and refund them to my address:1BW4GWrYtdTSwHz175D6LSaQuFmrq39dHL
