Thank you guys for your input.
I have now been reminded that electrum is open source.
I understand where you are coming from, I appreciate your comments.
I get where you are coming from when you say "If you receive a malicious message via whatsapp, it's not whatsapp's fault".
But you read everywhere to only download or update software/apps via the proper website or app - that's exactly what I did - the notice to update came via the app whilst doing a transaction. If you opened an app like photoshop on your computer or phone and it asked you to update before you could use it again, most people would follow the link because they trust photoshop, and if it crashed your computer, you would blame photoshop for not warning people.
As soon as it happened at the time, I researched and found out immediately that this was an on going problem - so why didn't the developers have a notice front and centre warning people, or even freeze transactions until the problem was rectified?
Anyway, I understand that the money is gone and I can't blame anyone because there is nobody to blame and the legal stuff covers any liability.
The blame comes back to me for trusting the wallet too much in the first place. You would think that a crypto wallet would have that sort of thing covered.
My real hope was that someone would reply and say "They've found a way to trace the transactions and the people who got duped can put their names on a list to receive some of their money back" - but I know that is like living in cloud cuckoo land.
But I live in hope.
Thanks again guys.
