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

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?

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!
