Address reuse is like wearing a giant name tag all around town. Every time you reuse the same address for incoming payments, you’re effectively making it easier for observers to link those transactions. It’s a common rookie mistake, especially among new Bitcoin users who aren’t aware of how the blockchain’s transparency works.

By not generating a fresh address, you allow blockchain watchers to see a clearer pattern of how much BTC you’re receiving or spending over time. It’s also considered poor wallet hygiene. Most modern wallets automatically generate a new address for each payment to improve your privacy and security posture. So, if you find yourself reusing addresses, think about rotating them—just like changing your socks every day.
