Envisioning the digital tech deeply the thoughts of privacy have died away for wants to track criminals. The privacy never stayed, staring at the responses above me. Not Trying to complicate the thread, was there ever a certain day where the network was private and people staying truly anonymous and untracked?
People are anonymous in the blockchain, only your transactions are tracked, no name or identity is attached to your wallet, therefore no one knows who own a particular wallet unless if it is a centralized exchange wallet. According to the overall story, Jimmy was caught after sending $800 worth of Bitcoin to centralized KYC exchange, which means since he stole the Bitcoin, his bitcoin wallet address was under watch list, but nobody knows the owner of the wallet until he made a transaction to a centralized exchange wallet that reveled his identity because if the KYC he submitted in the exchange.
This is another reason to avoid CEX.
