My question was aimed towards exit nodes:
Is it safe to use web wallets (with https://)? (can exit nod for example change address, where I’m sending BTC, can it steal my login information?)
Is it safe to use desktop applications (Electrum)? (can exit nod change for example address, where I’m sending BTC, can it steal my login information?)
I’m not aware of any anonymity risks.
All traffic (browser, desktop wallet) is going through Tor on Whonix. And even if my IP somehow leaked, I’m not aware, that transactions would store IP of sender in blockchain.
As blockchain can be view publicly, I’m aware, that it’s possible link transactions between BTC addresses. This chain of evidence can be broken by exchanging BTC to Monero (not sure thou, never tried it).
