Getting hacked is such a very disappointing experience. Your experience of yours serves a lesson not just for you but for us here on this forum. More often investors fail to protect their account because most of them do not know how to erase their footprints online. Being cautious at all times when we access our Bitcoin wallet significantly increases the safety of our account. The recovery of your Bitcoin is hardly impossible. However, you can report the incident to your Bitcoin wallet provider. They might ask you for some details, but there's no guarantee that you'll recover your funds.
