Can I find my bitcoin private key?
If you loss your private key I don't think that you can be able to find your private key when you lost it,
the only way if you can recover your private key is when you document it by writing it out and save it to Somewhere that is only way that you can recover your private key but a process whereby you have misplaced your private key and don't think that it will be easier for you to recover their private key or your seed phrase
That's not the only way to wallet private keys, though, if the person still has access to the computer where the Bitcoin wallet is downloaded, but only forgot the wallet password.
The person can try password recovery through the use of variation, brute force with the use of hashcat, or BTCrecover (if they have the password idea).
We can only say that the only way to rectify the wallet is through the private key if we lose access to the exact wallet app computer.
