It's important to note that while tracking transactions on the public ledger of blockchain technology doesn't reveal the intricacies of Bitcoin transactions and public keys, it may facilitate the linking of multiple addresses together for further analysis. Virtual Assets Service Providers retain transaction data for Bitcoin addresses associated with exchanges, custody wallets, and custodians that cater to individual and business clients in the cryptocurrency space. The information collected during registration, known as Know Your Customer (KYC), enables the tracking of a user's real-world identity. These data can be connected thanks to the use of blockchain technology. Additionally, you can trace your Bitcoin transactions using tools such as Bitcoin Explorers and other similar resources. I will be glad to get more contributions on how I can maintain more privacy.
To have a total privacy while using Bitcoin then one needs to stop using centralized exchanges where Kyc is needed for account verification and focus using only decentralized exchange such as "bisq.net" which supports only desktop, and both buying and selling of Bitcoin. Or probably use mixers in mixing your coins so as to enable clear bitcoin transaction history on the blockchain. Which are both nice ideas
