I'm hacked victim,I used my etherwallet to received my assets..
I don't understand what is your problem?
How can anyone take your private key by sending ethereum to the address?

I think you may entered into the clone MEW website where the hackers used to copy your private key and then your funds were stolen.But any probide your wthereum address then we can understand what was the problem here.
he got scam so that's a big problem
.but why hacker know my pivate key? Hacker is sent ethereum into my wallet and used as a gas to get all my coins..how it all happened guys.?
i think private key here is so secure but if you really experience that kind of thing i think you got scam because they know you in real life like they use your phone or i think the transaction can be trace here in crypto so better to post this in web wallets for more information about this scam there's a lot of topics about this MEW scam there
