## Definition

Pseudonymous is the right word for most crypto activity. You are not anonymous: every transaction you send is linked to a wallet address that is permanently visible on chain.

You may or may not be linked to a real-world identity, depending on whether you have ever connected the address to a regulated service. Skilled chain analysts can build detailed profiles by following the flow of funds.
