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.

Quote from: hosseinimr93 on June 13, 2023, 09:54:52 AM

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.

Quote from: NotATether on June 15, 2023, 06:22:14 AM

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.

See the warning below:

Quote from: Blockchain Explorer

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.

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

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.

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.

Quote

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.

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.

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.

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.

...A big Thank You from me...

It's over a month since I've been looking for an answer on the internet but there was none, I guess it's time I ask my seniors in Bitcoin affairs about it.

Recently, I noticed a Risk Warning from Blockchain Explorer on my transaction, and when I checked I discovered the warning was due to sending "Everything" in that wallet address to another one.

See the warning below:

Quote from: Blockchain Explorer

Note: The quote is not clickable because I don't want to reveal the transaction involved for privacy reasons.

Do you mean that if you tend to transfer large amount of funds, with the use of centralized exchange tracker you are concerned if someone might know your transaction details such as your address and information. So instead of transferring your funds on one big transaction, you will divide it into many.

If this is the case, the whole balance transfer would still reflect. BUt don't be too wary because it's just most of the time the Transaction address is only information seen. Dividing your transfer might cost you fees but if it will ensure greater level of security and assurance, then it will be worth it.

I think the warning relates to the previous sentence about how stalkers including investigators can usually more easily identify addresses connected to an exchange wallet (especially if it's KYCed). The large number of transactions from exchanges can be a conclusive reason that the coins are actually still under the same ownership.

Kind of makes sense...

But of the two transactions, that is

sending coins all in one transaction
or having to split your transaction in multiple of them, which one has a high chance of compromising one's identity

I thought all have an equal chance of masking your identity and making it difficult for transaction stalkers to find ones identity, and especially if wallet addy is a one time use only I strongly believe would have a tough time to make a successful tx analysis.

No any threat to your security (security contents differs from privacy) but so long as you use Blockchain Explorers (which are not yours) to examine your own transactions there will be a treat to your privacy as most of them belong to agencies ( or cooperate with them) that do chain analysis in the service of the state surveillance bodies. Those Blockchain Explorers log your IP and keep records of transactions your are interested in.

Regarding warning message.Take it as heuristic used by chain analysis (ChA) i.e if you move the whole of your stash from one address to another one ChA will assume that both addresses are yours. If at least one of those two addresses is already linked somehow ( or will be linked) to your ID then transaction involved compromises your privacy.

To not immolate your privacy when moving your fund from single address it is always better to split it into not round parts and send those parts to two or three or even more addresses, sure, one part to single address.

In my first experience in sending bitcoin, I also wondered about the warning message. But then I browsed and found out what the intent of the warning was, which really wasn't a warning to worry about because it was just a suggestion to increase privacy security for us. And usually the solution is to use a mixer, our privacy can be maintained.

Even on Blockchair we can see our privacy security level from weak-medium-high. And when I tried to use the Mixer, I managed to get a high privacy level.

To find out more details about increasing privacy, you can read here https://blockchair.com/bitcoin/privacy-o-meter/

But I personally very rarely use it except for shipping to my long-term investment wallet which of course I try to maintain its privacy.

You have gotten great answers from BitMaxz, Charles-Tim, and Hosseinimr93. But anyway, I believe that might not be what you meant and since you have the answer to your question, I will suggest you lock this thread.

On a normal day the exchanges will prefer you have some amount of sats left for you to remain on your wallet aside that it also important to increase your privacy with splitting your coin, which means there's a bid for more privacy while using your bitcoin through the wallet type used ad another thing is to be security consciouss, but in this case, no threat to the security in sending the entire bitcoin, also for the privacy reasons, it only increases the chances but not 100% guarantee on privacy if you eventually split your coin on multiple transactions.

It's just a tip and shouldn't be assumed for threat or warning because it's has nothing to do with the coin you're sending, afterall blockchain is an open distributed ledger which by default everything is meant to be open and seen by anyone except you choose not to allow that by going for more privacy measures.

Note: The quote is not clickable because I don't want to reveal the transaction involved for privacy reasons.

The coins you are withdrawing from a centralized exchange have already been associated with your identity: all the UTXOs used to construct a transaction have the "KYCed" status, which means they can freely be consolidated, merged, etc., without further compromising privacy. Privacy doesn't exist in this case, you can't make it worse. However, in your personal wallet (not an exchange account), you may have coins of different history, including coins coming from CoinJoin, mixing services, or centralized exchanges. Some of these UTXOs are not yet associated with your documents, so you probably will want to separate KYC and non-KYC bitcoins to prevent a potential observer from figuring out how many coins you have. Ideally, you should label your addresses, transactions, and UTXOs to keep track of sources that coins arrived in your wallet: when spending, it is important to know whether you make an anonymous payment or completely transparent one.

Assuming you have 5 BTC and someone ask you to send him 0.0005 BTC, the person can easily know on blockchain explorer that you have 5 BTC. If you have splitted the 5 BTC in different transactions to different addresses, it gives you more privacy.

What's the point of sending from one address to another when the sending address can easily be detected and still traced back to you, and the receiver will know you own all 5 BTC?

Just adding a little more here- when we use a round amount in the change address and a random amount in the actual output, it's better because we always send a round amount and keep the rest as change which can be an easy sign to detect which address is the change address.

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

Yeah true unless you are splitting them through the help of a mixer. Splitting by mixer would be fine and with coin control, we can take care of the rest to ensure we aren't linking up.

It is about change address and UTXOs.

If you notice, when you withdraw your bitcoin from your exchange account, that exchange will proceed your withdrawal request together with other users. They will make so-called batch payment to multiple users in one transaction. And they always have leftover amount of bitcoin in their wallet.

Back to that warning. If you send bitcoin to yourself, you will move all your bitcoin from address A to address B. It's very likely you will move your bitcoin like this.

You can use the two blockchain explorers to check some transactions and see their analysis results and warnings.

They have some guides, articles about transaction privacy.
