Please recommend a wallet that can see the private key and only store Bitcoin

[Jeralhong]

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.

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).

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.

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.

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.

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？

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.

All wallet do implemented BIP39, so any wallet can recognize any seed pharse generated on other wallet since they're work same. If you can't import your seed pharse or the wallet doesn't have such features, pretty sure it's custodial wallet.

Don't need to worry if your private keys always change, it just for better privacy. If you don't want your private key changed, you can use electrum.

so if you transfer seed from coinomi to tronlink you'll have your money not on first or second but on say 16th wallet in the list. example made

[hugeblack]

Unlike hardware wallets, there is no open source wallet that offers multi-chain service, and therefore to choose an open source wallet that has been well reviewed, it will be single-blockchain wallet (some wallet generate the private key with the same master private key/seed, but you need to connect to a different network to manage it such as MetaMask with BSC/Polygon/Ethertum)

For Bitcoin, there are many options that you can find here ---> https://bitcoin.org/en/choose-your-wallet

For altcoins, I recommend using New/MetaMask, as it enables you to get the most tokens.

Generally, any two wallets using the same seed phrase will generate the same private keys and addresses, but there are caveats and exceptions.

"Private key" is a term with very specific meaning. A seed is not a private key. A wallet typically generates a new private key for each transaction using the seed phrase.

• Address: Bitcoins are sent to an address. An address is derived from its public key. It is not a public key or a wallet.
• Private Key: Used to control the bitcoins at an address. A private key is not a password or a seed phrase.
• Public Key: A public key is used in a transaction, and it is rarely seen, except in a transaction. A public key is derived from its private key. It is not an address.
• Wallet: A wallet contains and controls private keys and their associated addresses. A wallet is not an address. A wallet typically uses a seed phrase to generate its private keys.
• Seed/Mnemonic/Recovery Phrase: Used by a wallet to generate private keys and their associated addresses. A seed phrase is not a passphrase or a private key. A seed phrase is also known as a recovery phrase because all of a wallet's private keys and associated addresses are derived from it.
• Passphrase/password: A passphrase is used to encrypt a wallet, private key, or seed phrase. A passphrase is not a private key or a seed phrase. However, sometimes a seed phrase will contain an extra word that is used like a passphrase.

Here are sets of terms that are frequently confused with each other:

• Public key <==> Address
• Address <==> Wallet
• Private key <==> Seed/Mnemonic/Recovery Phrase <==> Passphrase

Terms that should be avoided because they are ambiguous or are probably being used incorrectly:

• Wallet address: There is no such thing as the address of a wallet. As stated above, a wallet contains private keys and their associated addresses.
• Public address: Use of this term typically indicates a confusion between the terms "address" and "public key". All addresses are public.
• Public Key: Typically, this term is mistakenly used in place of "address".

I know you want to own the private key, which is exactly the approach you should be taking, however you shouldn't be seeing your private key all that often. In fact, I'd say you only see it when backing it up the first time your generate it. You shouldn't be entering your private key each time, and you shouldn't be keeping a digital copy of it either.

Now onto the wallet, the recommendations have already been suggested, but it all depends on your intention. ColdCard is brilliant for creating a offline air gapped wallet, but it's complex to setup, and you lose a lot of functionality if you want to be accessing that Bitcoin often. For example, purchasing things, or trading. You could potentially use a ColdCard as a hot hardware wallet, but I don't think I could justify the cost, and loss of features that the ColdCard excels at, so I would probably look at a Trezor or similar device, since those are pretty much designed to be accessed frequently, and the initial cost of them is lower than a ColdCard.

Otherwise, it probably has to be Electrum. Electrum is free, and depending on the way you setup your wallet, and your personal threat level could b enough for your situation.

There are several wallets that are bitcoin only, but the one that I have used the longest is electrum, the wallet is easy to use and it allows you to both backup your seed words and your private keys with ease, now with that being said, even if the wallets that allow you to store multiple coins are not as secure and in some cases their code can be closed source, at the same time they do allow you to see your private keys, or at least that is the case with the Exodus wallet, but it is not an option that is enabled by default.

From what i understood from OP, every time he made a transaction, he can see that the rest of his holdings have been moved to another address (Change address) so he thinks that the private key have been updated which is absolutely not true. It's clear that he doesn't know about the all the private keys being combined in a single seed.
My suggestion for him is Electrum client which i always recommend for both experienced users or new comers because it has all the features with a friendly-use interface. Better than Electrum, i recommend using a physical hardware wallet for staking considerable amounts .

Electrum is really not very friendly to laymen, hahaha. But I'll study it with my heart, thanks again.

[alexeyneu]

and another thing on that. If you do export private key in tronlink and then import it you'll get non-hd wallet . it'll be one from the seed generated chain, but this time it used stand-alone. And you'll not get addresses or money on other wallets same seed.

Electrum seems to be the best non-custodial client for bitcoin. It's an original bitcoin wallet which works only for bitcoin (another version also designed for Monero if i am not wrong). If you can not get familiarized with Electrum, other clients will look so sophisticated for you especially when you look for a specific feature as there are no fuly detailed documentation for each client.
I found this tutorial that can help you familiarized with Electrum (Setup) : https://www.youtube.com/watch?v=2MP_EMxypCE
If you can well practice english then this wiki can help you better : https://electrum.readthedocs.io/en/latest/
However if you wanna try another client, i suggest you to choose from this list : https://bitcoin.org/en/choose-your-wallet?step=5

Since you are looking for a wallet that only works for bitcoin, maybe you can chose electrum.
https://www.investopedia.com/best-bitcoin-wallets-5070283#:~:text=Mycelium%20is%20an%20open%2Dsource,similar%20to%20the%20Electrum%20wallet.

Why you chose Electrum? because is it secure, open-source, and offers advanced features and options.

PROS AND CONS
Pros
Customizable transaction fees
Greater level of security than most hot wallets
Cons
Bare-bones user interface
Only works for Bitcoin

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.

Cons
Bare-bones user interface
Only works for Bitcoin

I knew you just copy this to one of investopedia article, but you don't need to emphasize that having only bitcoin wallet is a cons when someone asking a bitcoin-only wallet. And I don't think it is to be considered as a cons its a secured and the most recommended wallet.

[alexeyneu]

you don't have a password from server electrum runs on (electrum-server). electrum is opensource is stupid stuff
