Can I find my bitcoin private key?
Private key is not something you can easily lay your hands on. Also it depends on the kind of wallets you are making use of, if it is exchange wallet you can't possibly have access to the private key. However if you are making use of non custodial wallets then it is possible for you to have access to your private keys, you can even export your private key from the wallet. Therefore , it totally depends on the process we undertake while creating our wallet. If the wallet was actually created by you and during the process you saved your seed phrase then you already have access to your private keys however if you are making use of exchange the possibility of having access to your private key is not there.
By your first statement, I believe you mean private keys is not something that one can temper with in order not to expose it otherwise you make it looks so complicated by saying it's not something one can easily lay their hands on. Of course, you can easily lay hands on your private keys but allowing others to lay hands on it is a deadly mistake.
Op, did you just create a Bitcoin wallet and you want to get the private keys? Or do you have existing wallet but you lost the private keys? Your answer to this question will help the community to provide helpful information.
Mind you, if you're operating with exchanges, you can not have access to your private keys because you only create an account with them while they generate a wallet for you. Consequently, they also preserve the private keys to your wallet with a right to freeze and unfreeze your assets.
