Bitcoin transactions are not anonymous but users can still add a layer of privacy by using different addresses and other techniques to confuse blockchain surveillance. However, a de-anonymization method known as a dust attack is on the rise. If the microtransactions that characterize a dust attack go unnoticed, they can potentially be used to identify cryptocurrency users.
