Whoever gives me a satisfactory answer receives...

I don't think you have issues with your account or any security breach. Reasons why you're receiving the message above is because you're trying to empty your wallet to another one and the system is warning you to authenticate your wallet security so you don't get your account exposed to a scam. I think it's just a safety precautionary measures that the system practices to secure your privacy.

There is no risk when you are sending all your funds out of your wallet, the message is not related to scam, wallet authentication or other whatnots that you have mentioned, it is just an advisory message that can help with privacy, though mind you that only this cannot protect ones privacy, you can send your funds to different addresses or ensure that whilst sending funds out it has a change, but the addresses can still be connected to you, if you want to bolster your privacy, you must be careful with the exchanges and services that you use from the beginning, because once privacy is lost, it becomes too hard to get it back.

It's not a warning regarding your transaction its just a notification or notice to your transaction just like an announcement for every reminder for the users who always made a transaction, we cannot deny that there's an instance that the user made a mistake for the address and make a whole transfer of the funds, the reason why they recommend to participation those transactions to prevent this cases might happen, you don't need to worry if your address is right.

To me, whenever I encounter such a warning message, I always feel it's not because of how I send out the bitcoin. But it's because it's safer to send it out bit by bit. In the event of an error in the receiving address, the amount to be considered lost won't be that much.

Wrong.
As already mentioned, the warning is related to the privacy and it's displayed by blockchair.com when there's only 1 output in the transaction. The warning has nothing to do with one's security and the amount of bitcoin that is transacted.

This message is talking about transactions that have one input and output,

Blockchair.com displays that warning for any transaction that has only 1 output, even if the there are multiple inputs.

If you are withdrawing funds from an exchange, it is okay. If you're moving funds to another wallet, do not transfer the whole amount to another address. It greatly compromises your privacy.

The question is how? What is the security threat here?

My understanding is that, it is just one caveat that it is not dangerous for your privacy, overall, i have withdrawn all my balance via Blockchain Explorer network, everything is fine, but i have no problem with the privacy of the exchange, my wallet so far, i do it often, no problem, it's not a clear threat, if i consider it.

Unless you do this. privacy

How can people steal bitcoins when a bitcoin has a blockchain, a record of every transaction a cryptocurrency, like bitcoin has ever been used for?
They have to steal the account information (password), For example, to access your account you need the private key, if someone steals that, they can send the funds to another wallet.

I think you are still safe, even if you make transactions from exchange A to exchange B, wallet A to wallet B and so on, even if you send all balances until they are empty.


In my opinion, this answer is right to clear your doubts about transactions through Blockchain Explorer, even though there are such warnings.

Without sharing your bitcoin address, it is not possible to receive funds from another party, so you have to share the Bitcoin address without a second option. Now the question arises that what can happen to my address once you make it public. Hackers can manage to find your address, but cannot do anything until you share them your private keys. The private key can be understood like the password for your bank account for transaction requirement, thus without revealing your private key, people can locate your address, but cannot peep into your account details or be able to do any transaction.

These addresses are not crypto wallet nor balance accounts. You can use it to receive the crypto funds. These addresses are just like bank account numbers where other parties can see and deposit, but they cannot withdraw or send money from that account. Only the owner of the address has the power to send money if he/she has other private keys. Bitcoin address has a built-in check code, so no one can send the bitcoin to wrong address. If the address is valid, but without an owner in such cases the coins sent mistakenly are lost forever and cannot be reverted.

My thinking is you are still safe, against the warning, even though transferring the whole thing.

Thank you everyone for the contribution so far, I think I know the answer and the winners already, but still reading...

The question is how? What is the security threat here?

The only problem is you didn't read the warning carefully there is no security threat mentioned in the warning but talks about privacy.

I appreciate you pointing that out, I later discovered the error, it's a mistake on my part. I wanted to write a Privacy threat instead of a Security threat, it's actually a personal error. Let me say that the Security threat is more programmed in my head than the Privacy threat, so I just chose the one that ranged most.

Still, if one is not careful, it's a matter of time a privacy threat would become a security threat...lol

See the warning below:

If you are withdrawing funds from an exchange, it is okay. If you're moving funds to another wallet, do not transfer the whole amount to another address. It greatly compromises your privacy.

The question is how? What is the security threat here?

I don't see any security threats here and I've read your thread for more than 5 times trying to figure out the threats but didn't see any.
I guess blockchain explorer was only worried  about your security as it is unusual  of you to suddenly withdraw  all your funds from one wallet to another which is one thing very common with criminals as soon as they get any access to your wallet, what they  simply do is transfer all your money to another wallet and since this happened,  I think they're  just trying to make sure it was you carrying  out the transaction and not some  criminals.

You have a nice thread topic by the way because it will typically attract alot of people to your thread.

And the winner goes to...@hosseinimr93 and @NotATether for the below quotes;

The warning mentioned by OP is displayed on blockchair.com when a transaction has exactly 1 output and it has nothing to do with the amount you send.
In the case your transaction has only 1 output, you will see that warning, even if you send only 1000 sat.

Blockchair.com suggests not sending the whole balance, so that the transaction has a change.

With using a change address, you can confuse blockchain analyzers to not know which of the receiving addresses is owned by the recipient and which of them is the change. That's why blockchair.com suggests having a change. But you don't really need to always do that and you are right. That's not accurate. If you make a transaction with only 1 output, it's more like sending the fund to yourself or making a deposit to an exchange.

You can surely improve your privacy in that way, but those addresses are still linked with each other somehow.

This message is talking about transactions that have one input and output, because it is trivial for on-chain analysis to conclude that someone is simply moving around their funds, as opposed to sending it to someone. And actually, one-input and two-output transactions also have no privacy, as the second output is usually "change" that goes back to the sender's wallet.

Transactions with multiple inputs and outputs are excellent as they are indistinguishable from coinjoins.

I've always known that this forum lies the answers to the questions that one could think most hidden, even the hidden ones to the internet.

A special and big Thank You to you our senior members as I promised!

I am locking this thread now.
