In case of a compromise of one of your devices, an attacker can spend digital cash from your wallet. Checking your balance might reveal to you whether your device has eventually been compromised. If a coin has been spent, this coin cannot be spent a second time. The Exchange examines every coin whether it has been spent and thus makes double spending impossible.
