You cannot directly know who the owner of the Bitcoin address is, if you use a Custodial wallet and a crypto exchange that asks you for KYC verification then they will know your identity, even if you are found to have problems then the government can ask the crypto wallet or exchange to freeze your account , but if you use a non-custodial wallet then no one can access your account, because you hold the private key. Meanwhile, Bitcoin hackers only trace transactions on the blockchain and where Bitcoins are stored without needing to know the account owner.
