Although the transactions themselves can be tracked, it can be extremely difficult to determine the exact owner of a crypto wallet without additional data. Many users prefer to remain anonymous, using various methods to enhance their privacy: from creating multiple wallets to using mixers to obscure the traces of transfers.
However, if the owner of the wallet has ever used it on an exchange to buy or sell cryptocurrency, this data can be the key to identification. Exchanges are required to collect information about their customers as part of KYC (Know Your Customer) requirements and can provide this data upon request from law enforcement agencies.
There are also other ways, for example, users themselves can unintentionally reveal information about their wallet. For example, they can mention their cryptocurrency address on forums, social networks, or on various platforms where transactions or donations are made. OSINT and social engineering can also help to establish the owner of a crypto wallet, but these methods are not always legal.
Another professional way to analyze cryptocurrency transactions is ****address clustering, when several addresses are combined into one group based on common features and behavior. This method allows you to determine that several addresses may belong to one entity. This can be done using artificial intelligence technologies that analyze activity patterns and identify connections between addresses. Clustering helps to more accurately determine the owner, even if he uses several wallets for anonymity.
