I believe AI will indeed make blockchain data analysis much easier, which could affect user privacy. However, I don’t see it as a direct threat to Bitcoin’s decentralization, since the network rules and consensus remain unchanged.
What this highlights is the need for users to adopt stronger privacy practices—such as mixing services, confidential transactions, or upcoming privacy-enhancing tools.
In the end, while AI may make surveillance cheaper and faster, it will also push innovation in privacy technologies. So instead of being only a threat, it can also be an opportunity for the Bitcoin ecosystem to evolve.
