For the first 4 days that was the biggest one with me and maybe still is as to how my 2fa could be switched off, they would first need to get around my 2fa to switch 2fa off if you get my meaning.
If you search a bit online you will very easily find a lot of information on how to hack/bypass 2FA, so although I'm not claiming that it happened to you, you have to admit that someone managed to find a way to disable your 2FA protection -
here's an example of how it can be done, and keep in mind that the article is from 2018.
The reason I mentioned the £23, £46 and £65 sums is that it could have been a sign that blockchain.com's software had screwed up.
Very easily possible, because I also used that service in the past and I encountered all kinds of situations, even with incorrect balances.
But I have to admit now the biggest clue is the Electrum thing, only 6 items logged in it's entire 2 year history and they happened within minutes of my money vanish in blockchain, but what is the connection, nobody can give me an answer
.
From your introductory post, we can conclude that you had certain problems with blockchain.com around 2021 and then you decided to install Electrum - and then I assume you used the option to enter your seed from blockchain (or maybe you just import your BTC addresses and created a watch-only wallet) - do you remember if you did that? This would explain the fact that you see identical outgoing transactions in Electrum and blockchain.com - because they both share the same seed, that is, the same addresses/private keys.
If what I wrote is correct, then the only question is whether you left that seed unprotected in any form and someone managed to get hold of it - or are you a victim of some other exploit that exists on blockchain.com.
It probably has nothing to do with your case - but it reminded me of something from the past ->
Blockchain.com scam - lost fundsInteresting points and at least someone who is asking the same questions as me.
You have to just trust me in that nobody gets anything out of me in anyway when it comes to Bitcoin, I am that bad that I am reluctant to even tell people I have it.
The only information(not shared though) was when I attempted to use my seed phrase in Electrum to import my Bitcoin which was then classed as a very secure wallet and the only place ever I attempted to use it because back in 2021 thousands of us panicked when we thought blockchain had screwed up.
