please please help me , this coins is all i have and i now haven't any coin in the wallet .
I am very sad about what happened
First of all, blockchain can't "be hacked" like RawDog said, nor can you get the funds back through that "keys.lol" website. I'm not sure what's up with the trolling but anyway..
Blockchain Support can't help you, nor can we... if some automated malware got your funds stolen, they're probably gone for good so you can't really do much about it.
As far as I can understand, it wasn't
you who initiated the transaction, right? To me it sounds like some automated script that detects Blockchain Wallet login and sweeps the funds out of it. If it was automated, then it means you most likely had a malware on your PC either through browser plugins or infected downloads..
That's the thing with Bitcoin - nobody controls it so we can't do much especially as it wasn't some kind of mistake we can help you with.
It's hard to take the loss but man yourself up and move on - it could happen to the best of us.
EDIT: oh God, the shitposting is moving on to a new level every day..
You have to appreciate the humor. Yes it is an expensive loss and I am sure we are all feeling for OP right now.
Bottom line, you need to see if your device is infected with malware. As for the missing Bitcoin you will not be able to get that back.
