Which crypto is not trackable?

Can you clarify which specific aspect of crypto you're referring to when asking about a crypto that's not trackable? Cryptocurrencies themselves are generally designed to be traceable through their decentralized ledger systems, known as blockchains. However, there may be specific use cases or privacy-focused coins designed to obscure or obfuscate transaction data to varying degrees. For example, some cryptocurrencies utilize privacy features like ring signatures, stealth addresses, or mixing services to enhance user anonymity. But it's important to note that even these privacy-focused coins can still be tracked to some extent if the proper investigative methods and resources are applied. So, the question of "which crypto is not trackable" may not have a definitive answer, as it depends on the level of privacy and anonymity the user is seeking and the specific cryptocurrency being used.
