Address reuse gives observers a stable identifier that accumulates balances, transfers, token holdings, application interactions, and counterparties over time.
Why reuse is a strong signal
No amount or timing heuristic is needed to connect activity occurring under the same address. The ledger already groups it.
What a fresh address changes
A fresh address begins without earlier activity, which limits simple historical lookup. Its funding, first receipt, and later behavior can still connect it to other wallets.
Account and UTXO differences
Account-based chains commonly reuse one address, while Bitcoin wallets often generate new receive and change addresses. Both models can reveal relationships through spending behavior.
Practical boundary
Avoid unnecessary reuse where it fits the wallet workflow, but do not describe new addresses as anonymous or unlinkable.
How to read the evidence
Wallet privacy is cumulative. The route, browser session, wallet connection, gas source, receiving address, exchange account, public profile, and later transfers can each add a different relationship. Review those layers separately and avoid treating one fresh address as a complete solution. The most useful objective is minimizing unnecessary links while keeping recovery, address verification, and transaction safety intact.
