Dear Darth, can quantum computing hack/decode Electrum's master public key which was accidentaly leaked on the internet or random Electrum servers? We already know that single public key can potentially be decoded by quantum after spending UTXO from address so address reuse is rightly discouraged.
Can random Electrum servers actually see my master public key while they are used for watch-only wallet? Or they just see addresses which are currently used and also ones with previously spent coins?
Thanks in advance dear Darth!

QC is a buzzword. Forget it. It was launched only to scare the shit out of clueless people, to make you buy products that are "QC protected"... If you believe in that bullshit QC, sell now all your sats and forget about Bitcoin.
A public key cannot be "decoded". Most of what somebody can get from a pubkey is a a bunch of addresses linked to that pubkey. But they cannot do anything with that. Totally useless.

Yes. Better use https://bitcoin-safe.org with a neutrino sync if you do not want to reveal your xpub. The problem is not that you reveal your xpub, but you link it to an IP/identity. A random xpub means nothing if is not linked to a real identity.

Thank you very much for these recommendations. I now have my own full Bitcoin node and EPS connected to it but at the very beggining I've accidentally connected to 10 random Electrum servers so I leaked my IP. Since few years passed since that, do you recommend me creating completely new wallet from new seed and move coins there for max privacy?

Nah, don't be so paranoiac. Nothing really will happen for that "accident". The question is: from WHO you are really so scared? You know that fear is a tool of control, right? If you can control your fear, nobody can control you...

Nah, I'm not scared, if I was I would've already created new wallet. :)
But thanks for calming words. I've read almost all your guides so I'm not exactly a n00b xD

I've read almost all your guides
But seriously now, give it a try to bitcoin-safe wallet, using a neutrino sync is really cool and no need anymore for all that heavy duty EPS and shit... But yes, if you already have an EPS, don't throw it away, is still useful.
