Using open-source and non-custodial wallets like electrum or wasabi wallet, you have full control over your bitcoins. Limit storing your bitcoins on exchanges, it is very risky to give your assets to third parties to hold.
If you are a long-term investor and you have money, better buy yourself a cold wallet( ledger, Trezor).
Thank you very much, the amount of my assets has not reached the level that I need to keep it in a cold wallet. I'm just trying to find a balance between convenience and security.
... 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....
Most wallets now generate private keys based on a "seed phrase" (aka "recovery phrase"). Because the private keys generated by the wallet are always the same for that seed phrase, there is no need to back up every private key. You only need to back up the seed phrase.
Being concerned about multi-coin wallets with low security is fine, but any concern about a wallet using a unique address for each transaction is unfounded.
I get it. I used to think that the wallet was changing my private key, so I would re-back it up after every transfer. It turns out that only the seed is the only private key, and the others are salted.
However, is the seed of each wallet can only be used by itself and not each other?
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.
What official website are you talking about? And what recommendations were you given?

What wallet did you use before? Most wallets these days show the seed phrase rather than the private key for easy backup. And, after transferring bitcoins, the sending address might be changed to an unused one for privacy, but the seed phrase or xpriv remains the same.
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.
• Bitcoin core,
• Electrum.
Thank you very much. The official website is “bitcoin.org”, wallets such as Bitcoin Wallet, when using, found that the private key is always changing, but in fact the seed has not changed.
There is also a question, whether the seed phrase can only be used in the generated wallet, or can also be used in other wallets.
