I don't know how I Explain my feelings. I Just lost all of my savings money. I was holding since January, I have been Holding to make again a good amount of Money. But at the end, my holding's output is, I lost everything because of my ETH wallet got hack! Almost 5K USD Stolen. All of my hard working money. I Don't know how can hacker hacked my wallet. Because I Kept very secure my private key, My friends are telling that hacker hacked my wallet by my email address. But how can someone hack only by an email address?
I Got a security alert from Google that someone has your password after then I changed my password immediately. Then after some time, I was checking my wallet to check new Coin. And then I Shocked! I Just want to give up, can't think what should I do

This is very disappointing, I'm sorry for your loss. It is not easy to lose money in an instant specially being hacked. I hope you have consoled yourself now. Email address is not safe it is prone to hackers. Any online storage even messengers email inbox can be opened by hackers. Better if you print your pinkey in a paper or save in a usb or any external storage. Better luck next time.
