I know that feeling mate because last year I was a victim like you! After then I always told people do not use the Myetherwallet alone. Everyone should use a hardware wallet, you had 45 ETH and one hardware wallet price is only 100 USD almost. You should've bought a hardware wallet. I don't know there is any chance to get back your assets! Now, you have to buy a ledger or Trezor wallet firstly! Have patience mate!

Look for the addresses ETH was sent, maybe it is in centralized exchanges. Then you can get in touch with support, and they may freeze the wallet. The amount is too much. 

Are you asking us to pay for the funds you lost?

A big pass from me.

I almost guarantee what happened, he used other people's money, he wasn't using a secure hardware wallet and most likely just mistyped and logged into a phishing site.

Maybe you should start a fourth topic about this and see if someone is willing to send you free eth "help you".
No one can do anything for you, you've been told 50 times already. No need to call the FBI or the CIA lol.
Lock your threads.

If you have extreme proof that the coins we're part of a hack and the coins are sitting in the exchanges wallet, there is a chance they will freeze the funds.

Sorry to hear that i don't think anyone will be able to help you to retrieve back your wallet, you can only hope miracle will happen. Anyway what lost is lost no point pondering over it, let this be an expensive lesson to you maybe.

OP, take note of this.  It isn't likely anybody is going to be able to help you get your ETH back if it was really stolen, but either way you should at least give more details about what happened in the off chance you're just not doing something correctly with the wallet or whatever.  I didn't see any other threads, so I don't know if you described what happened elsewhere (and you should definitely keep it to one thread).

If you did get hacked, you have my sympathy--even with your lousy feedback.  That's an enormous amount of money to lose.

This is the third topic you have started in just a couple of hours. 1 and 2

I understand your frustration but please pick one and stick with it (lock the other two as you are breaking forum rules; cross/multi-posting).

No one can help even if you make complaint about these scam,the problem is with your wallet how did you let someone knows about your private keys.

No, I really doubt that they could, does your government have an equivalent?

Just putting some transaction ID does not make any sense. Please provide more info about the issue and how did it happend.

Was your private key leaked?

Did anyone unknowingly transferred your ETH to the other address?

Or how did that happen?

Just to let you know crypto transactions are not reversable and there are pretty less chances of you getting the funds back.

Can the FBI and the CIA apply for me?
not in my government

Sounds like it wasn't your money, there is nothing you can do. You can try to get the authorities involved but if your government doesn't have an FBI or CIA I doubt that it would do anything. Sorry

I hope you invested some of those ethers in a hardware wallet. Even a Ledger Nano S so cheap nowadays and it still sure gets the job done. Can you tell what wallet did you use?

I highly doubt you took all safety measures.

We're you using a hardware wallet with MEW? Which address was yours.
