My bitcoin is stolen and following is how it happened? A guy named, "David Robin" from Fremont,California US (obviously a fake one), connected in a social network told me that I can mine for bitcoin when I connect my blockchain wallet to the blockchain mining network with the help of a antminer s9 hardware. He asked me to register a blockchain account and send him the wallet id and password so he can do the connections. He also said that once he is done with the connections, I will change my password. I shared with him my user name and password information. He did something with it. I changed my password and then topped up the Blockchain account with 0.198899 BTC, approx. $3,200/- on 27/12/17. Within half an hour my wallet was empty. I will appreciate if someone can explain how it has happened and if there is any way to get my BTC back?
