0.00057762 BTC were sent to 1FLm7zXTqzAU9xNEe7pNY8P289WUvPwq6g.

4.00110683 BTC were sent to a change address, bc1qzfhvk5d3rnsnesy8l7c38plc4kcwz3ytuqvfge.

The sending address and receiving address are legacy P2PKH addresses. The change address is a Bech32 address.

I don't know why your wallet would create a transaction that puts the change in a Bech32 address if it can't show you coins in Bech32 addresses, but don't panic. If you can't find a setting in your wallet software to show Bech32 addresses, you should be able to recover that wallet to one that does.

What type of wallet is this? You said "blockchain", but blockchain (lowercase) isn't a wallet.

What type of recovery information--for example, a mnemonic sentence ("seed words") and possibly an additional seed phrase--do you have for this wallet?

[Charles-Tim]

I will advise you to download Bluewallet. Import your seed phrase of Blockchain.com wallet on the Bluewallet. The reason I advice you to use Bluewallet is because it can help you to automatically check for funded addresses and use it to detect if it is legacy or segwit.

You do not need to use Blackchain wallet. It is close source. If you are able to have access to your coins on Bluewallet, it would be better to generate new seed phrase on Bluewallet directly and send your coins to one of the addresses the seed phrase generates.

[Sayounes]

The seed phrase is the 12 recovery words right!?

[Charles-Tim]

The seed phrase is the 12 recovery words right!?

Yes. It can be 12, 15, 18, 21 or 24 word long.

[Sayounes]

It shows my last transaction
But I just sent 50usdt
And it shows-4btc
The transaction that I already posted here

[Forsyth Jones]

From what I understand, the remaining balance was sent to a p2wpkh (bech32 bc1q) change address, but blockchain.info wallet can't read it, right?

So, download bluewallet, restore using your recovery seed, if the change address is set to the BIP84 path (M/84H/0H/0H), you will probably see your balance there.

Remember to select segwit or p2wpkh during the restore.

After that, create a new wallet (backup it with the recovery words written down) and don't use blockchain.info anymore, these guys really try hard to destroy their own reputation.

[Cricktor]

The seed phrase is the 12 recovery words right!?

Yes, this is a common number of mnemonic recovery words, a list of 2048 words from the BIP-39 wordlist.

You should understand that those recovery words of your wallet have to be kept confidential. Do not type them into an online website. With these recovery words anyone could recreate your wallet and spend your coins. So be careful, as you don't seem to know much about how Bitcoin HD wallets work.

How do you assume or know the Segwit address bc1qzfhvk5d3rnsnesy8l7c38plc4kcwz3ytuqvfge doesn't belong to your blockchain.com wallet? How exactly did you check your wallet seems empty?

It doesn't quite look your 4.00110683BTC on address bc1qzfhvk5d3rnsnesy8l7c38plc4kcwz3ytuqvfge were stolen, because the coins didn't move at all so far. Stolen coins usually don't remain on the first foreign address of a thief.

I totally don't understand why you have ~4BTC on a blockchain.com wallet. I'd rather use a decent hardware wallet to secure such a sum.

But I just sent 50usdt

No, you sent 0.00057762BTC which is one of the transaction's outputs. As advised by Forsyth Jones you should abandon your stupid wallet or whatever can't properly recognize your change output.

How to select segwit or p2wpkh during restor

[Zaguru12]

It shows my last transaction
But I just sent 50usdt
And it shows-4btc
The transaction that I already posted here

There is probability that the 4btc was just a single UTXO and as such during a transaction the entire 4btc needs to be use and then the change is sent to the change address on that same wallet so with the private  keys on your hand you can spend from that wallet all the time. bc1qzfhvk5d3rnsnesy8l7c38plc4kcwz3ytuqvfge; this is the address on which your bitcoin is on and if you search with the other address it will show am empty address without bitcoin

 

How to select segwit or p2wpkh during restor

BlueWallet to me actually Restores or create a wallet in the SegWit format as default but you can use advance option during restoration to change script

[Sayounes]

I selected segwit
I can see my balance now
Gonna try send it to new wallet
Hope it work

Thanks brother

Yeah, same here for me, if bluewallet detects balance in native p2wpkh segwit, it will suggest you on the screen and probably show it next to the balance.

How to select segwit or p2wpkh during restor

Talkimg is down for me, I will use an alternative image hosting tool, if the balance does not automatically appear in the BIP84 derivation path, follow the steps in the images by clicking on the buttons I marked in red.

In short, if it doesn't appear for you, after entering the recovery seed, the wallet will scan for balances in known derivation paths, but if this does not happen, click on: Custom Derivation Path, in the next step it will show the available address type options, select the HD Segwit (BIP84 Bech32 Native) option to access your native segwit wallet.

This is strange, there is hardly a wallet that sends the remaining balance (change) to a different type of script, only 2 wallets that I know of that do this: Bitcoin Core and Coinomi (you have to enable it in the settings), it is probably enabled in the blockchain.com options to send the remaining balance to a different type of change address, but this should be optional (but I suspect that this option does not even appear in the user interface).

[Charles-Tim]

Remember to select segwit or p2wpkh during the restore.

You will see Bluewallet do that automatically for you. You will see it go through all the three derivation paths and also Electrum derivation path. If no address is funded, the default is segwit.

How to select segwit or p2wpkh during restor

You do not need to do that. You can understand the reason from what I just wrote above this quote. But if you want to learn about it, it is simple. After you click on 'import', you will see 'use custom derivation part'. Click on it and select 'HD segwit (BIP84 Bech32 Native)'.

BlueWallet to me actually Restores or create a wallet in the SegWit format as default but you can use advance option during restoration to change script

Bluewallet is now in advance option by default and it can not be changed to the old simple type. So that means it is not called advanced option anymore as it is how the wallet is now.

The information you got in an answer on Reddit is correct. I did not use blockchain.com wallet since years ago when I understand risk of close source wallet that blockchain wallet is.

I am not sure now they force their users to change from Legacy wallet to Segwit wallet after a user make a transaction from old Legacy wallet, but information on block explorer shows it.

OP already confirmed that (s)he can see the 4.xBTC on the Segwit address with likely a restored wallet on Bluewallet.

I don't recommend to hold little more than 4BTC in a hot software wallet, especially on a mobile phone. But it's your choice if you do it and proceed.

Make sure you setup a new wallet in a safe environment. Backup the mnemonic recovery words on paper, later maybe stamp them in house fire proof metal (stainless steel should be good enough). Do not store your recovery words in digital form, no files, no pictures or screenshots!

Check very carefully the receiving address of your new wallet where you want to send your 4BTC to. Clipboard replacement malware exists! Double check, maybe triple check. Check parts at the front, in the middle and at the end of a public address, don't skip this.

Check for a reasonable transaction fee rate at https://mempool.space/. If you don't understand enough, go learn some basics at https://learnmeabitcoin.com!

Better get a hardware wallet and I'm not speaking of Ledger crap. Ledger can't be trusted anymore.

I would like to store it in my computer, with 4 or more different wallets, with different strong wallet passwords for each too.

Storing all 4 BTC in one wallet, and on a mobile device like a mobile phone is very risky. Phone can be lost, stolen, and people can brute force wallet password to access that wallet and steal all 4 BTC.

If possible, use hardware wallet to store big fund like this.

Different wallets on an online computer are still a risk. OP should learn how to use cold storage, or get a hardware wallet.
Using a buggy online wallet and talking about USDT when making a Bitcoin transaction makes me think OP is just one step away from really losing his Bitcoins.

What must have happened is that your wallet contained one UXTO (unspent transaction output) for the 4BTC, so when you wanted to send 50 USD*, the wallet had to spend that output, because in the Bitcoin protocol, to send precise amounts, we spend UTXOs and create change addresses. The change address contained the rest of your coins, and so they couldn't have been swiped or anything like that.

*Are you sure you were sending USDT? Tether stopped supporting the Bitcoin network long ago.

[Sayounes]

Thanks everyone here
I said 50 usdt because I don’t remember the exact number on btc
It is equivalent to 50usdt when I sent it
blockchain.com is really bad right now very heavy and risky
I was just storing these from late 2017 there
Gonna look for a good cold wallet
Any recommendations is welcome

Just a thought: when I posted the issue on Reddit I got a lot of private messages asking to help
But they are just looking for my seed
Also an account on Twitter personalized blockchain support tried the same thing
Be careful everyone one

A cold wallet is a wallet that never touched the internet. You can use Electrum to set it up, but it's much easier and more beginner friendly to buy a hardware wallet. Trezor for instance.

It happens here too. Be careful who you trust.

DM first means scammers or at least it is early signal of potential scammers.
If they ask you private key, mnemonic seed, or require you to send them money, it's confirmation of scammers.

They're impersonators of company, platform staffs to find victims.

In Bitcoin and cryptocurrency, it's your private keys, it's your mnemonic seed, it's your coins. If you share your mnemonic seed or private key to others, you lose that wallet and any fund there.

The cryptocurrency scambook.
