Thanks! So electrum will never know who I am during this transaction?
That's how it's supposed to be but unfortunately we have been seasoned by the banking system and KYC we never took the privacy seriously.
Technically your Electrum can be more private if you run your own node and connected via TOR or the nodes you were connected to knows your IP and it's a privacy concern but it might not be suitable for beginners to start with unless they know what they are doing,
I am in more trouble than ever now - as I said I tried importing my keys to Blockchain.com first and thought it didn't work, but that address is now showing in my blockchain account. I also imported the keys into my new Electrum account and the balance is showing there but it says it doesn't recognise my password so I can't access it and it is a big chunk of money. It never gave me a seed phrase when I was opening it so I what can I do, I presume nothing! When I check the address on Blockchair, the full amount is there, I thought it would go down to 0 when I transferred it to Electrum?
