Address Reuse
Address reuse is the practice of receiving Bitcoin to the same address more than once, which is generally discouraged because it reduces privacy and, in a future quantum computing scenario, increases security risk.
When you spend from an address, the transaction reveals your public key on the blockchain. If you then receive more Bitcoin to that same address, the new balance sits behind an already-exposed public key. Modern Bitcoin wallets automatically generate a new receiving address for each transaction to avoid this issue.
