I will prefer not to use any telegram not for this reason, there is a wallet that I am using that has the characteristics but I am still using Electrum also on my mobile phone because it is a very good wallet. It is not up to what I need to sacrifice my privacy for.
As you seem to care about your privacy, it may be worth mentioning that unless you run your own server, even in electrum, you connect to servers provided by third parties and they can link your bitcoin addresses to your IP address.
Routing the connection traffic through Tor proxy can also help with privacy
to some extent when connecting to a public server.
At least, the provider can’t know the real ip behind a wallet even if they can see all other things about such wallet .Okay for network level imo ..
Depending on the privacy OP wants, it still go way down to UTXO and txn level, maintaining parallel connection from multiple source to prevent privacy leak .. Network level is still the only problem that can still link everything so you’re still right about running a node to create a private Electrum server
A Private server will only be useful for future privacy if the wallet itself already connected continuously to a public server unless he creates a new wallet and find a way to cut off trace and connection to his old histories .
General public privacy is usually enough though..
