Now that we're talking Gulden. I noticed that when I bought some Gulden my receiving address changed. Anyone knows if that is how it supposed to function? My wallet is showing the bought guldens but the original address is somehow gone / not visible anymore.
Yes, you will get a new address after each transaction, for privacy sake, so no one can see whats your complete stack. The old one will continue to function and is tight to your HD wallet recoverysentence.
But the client doesn;'t list this address anymore? How do you know which addresses you once owned?
