True. But, well, I supposed USD-to-BTC and BTC-to-USD services conceal this data to the extent recipient isn&#x27;t aware of sender&#x27;s address. This is usually not the case with &quot;classic&quot; services like bank-to-paypal-to-store chain (where PayPal requires you to identify and also would still provide a good insight of your identity to the store).<p>Also, I think there are coin mixers to avoid this.
