The developers are at fault that you have fallen for a phishing message ?
It is stated on the website (and on this forum and almost everywhere on the internet) that you need to verify the signature to make sure you are using the original software.

I am sorry to say, but only you are at fault. No one else.


Of course it is electrum faullt, because software has holes. I opened original programm not fake and it adviced me to down load upgrade, my fault is only that i have not learnt all these information before. But how do i know if i open ORIGINAL SOFTWARE!?





So you were storing all of your coins on a wallet shared between your computer and your mobile phone ?

It seems you need to reconsider how you store your coins. Try to acquire knowledge regarding secure storage of sensitive information. This forum is a good place to do so.
If the sum was really big, why did you store it on a computer which is connected to the internet, shared with your mobile phone  Why no hardware- or paper wallet ?


Again, the software was installed very far before and would never use in future, the money was safe untill i open that programm



Verifying the signature is common sense if you spend at least half an hour reading about securing funds.



I put m money on blockchaing and forgot about it , i am not sitting on forums



Just read what the website says and follow. Verify the signature and don't click on any link you see. As easy as that.

You know deep inside that you should have never left such a really big amount in a desktop wallet. That you should have bought a hardware wallet.

Desktop Wallets in your daily PC are just for a few bucks. Buy a ledger or a trezor and never lose money again.

The same thing won't happen again since it has been already fixed. Before the 3.3.3 update was released, Electrum had never notified users of available updates. You are the one at fault. No wallet is completely secure and bug-free.
