There's no way to know the owner of the transaction involving bitcoin. While it is easy to find which address send money to other address, but it is next to impossible to point out the owners of these addresses unless someone proclaims the ownership of those addresses! Probably that's the reason why bitcoin is still the preferred payment method in darkweb and that's a big reputation risk of cryptos! Moreover, bitcoin mixing services are present in the market to hide the money trail effectively! Like every technology has its positive and negative side, the same way it is a negative side of bitcoin use. Sad but true! Cipher trace can track transactions but not the owners!
