I don't trust exchanges, so I want to have a wallet with good security that can inquire private keys and only store bitcoins.
I see that many of the recommendations on the official website are multi-chain wallets.The applicability is good, but the security is not enough.In the wallet I used before, every time I transfer btc, the wallet will change the private key by default, which causes me to back up the private key every time I transfer btc.And I can't see my private key either, it's hidden by the wallet. This makes my private key especially easy to lose.
So please recommend a single-chain wallet that you think can query the private key and only store Bitcoins. The function is only to store btc, with high security, no other functions are required. For other functions, I will use a multi-chain wallet, and the money in it will be very small.

OVERVIEW
Electrum is one of the original Bitcoin wallets. It has been around since 2011, two years after Bitcoin’s creation, and has changed little since.12 While this wallet is bare-bones in terms of its user interface and commitment to only Bitcoin, it excels at this primary function. Electrum is also more suited for advanced users due to its complex options.
Electrum is open source, allows its users to set custom transaction fees, and has the option to choose between legacy Bitcoin and Segwit. It also offers users the ability to determine the level of security they wish to use. For example, you can create a standard wallet, one with 2-factor authentication, or a multi-signature wallet. You can also elongate your seed phrase with custom words.
Electrum is perfect for the more advanced Bitcoin holder who wants great security features and customizability, all in a simple layout.
