> So what good is keeping the coins in separate addresses then? Publishing of your public key slightly decrease security of your coins. While ECDSA is strong it's still safer when only hash of your public key (bitcoin address) is known. After all you can always end up with weak key due to software or even hardware bugs. > Am I missing something? You're completely right, but you underestimate how important that little detail is. If you only receive money to different addresses each time then until you actually start spending it's will be impossible to prove that you actually control any of these addresses.
