What is visible?
Bitcoin transactions are recorded on a public blockchain. Depending on the transaction and wallet behavior, observers can analyze addresses, inputs, outputs, amounts, timing, and relationships between transactions.
Why address reuse matters
Reusing an address can make it easier to associate multiple payments with the same on-chain identity. Fresh addresses can reduce simple forms of linkage, although they do not guarantee anonymity.
Wallet privacy
Privacy also depends on how wallets connect to nodes or third-party services, how transaction history is queried, and what information is disclosed outside the blockchain.
Privacy is a property of the whole workflow—not a single button or feature.
