You don't deal with me in any case, you deal directly with the OTC Address. As for proof of legitimacy, you can use this official link https://www.binance.com/en/vip-portal/OTC-trading-platform?ref=OTC-Spot, to contact the support to backcheck the Binance Enterprise ID used as OTC. I will be happy to provide it to anyone to who wants to check it by themselves.

Procedures are pretty straight forward.

You sent the amount you wish to be swapped to the OTC Address.
The OTC Address sends back the amount -2% of the token you wish to acquire.

Hi,

I offer my OTC BTC Services with a 2% fee (less than Binance) on any swap BTC/USDT BTC/USDC BTC/FDUSD etc.
Dealt threw a reputed OTC without a single faulty transaction (You can contact Binance directly and ask to check up the Binance ID)

For any concerns, Telegram @VICTUS_XMR.

Hi,

I'm looking for a genuine Satoshi BTC Seller, able to give a 6/3 discount on bulk amounts. I have a buyer willing to share both wallet address and Client Information Sheet to proceed.

Procedures should be looking like this:

Seller sends BTC wallet
Buyer sends USDT wallet
Satoshi
Handshake
Invoice/ SPA
USDT payment
BTC payment

Thank you

Re: Is Bitcoin Signature Messages still safe in 2024?

Not exactly sure what's the intent and the purpose of your message and I'd go with what I would request to be signed typically. The message would typically be:

"This Bitcoin Message is signed on 2024-08-22 at 1500 Hours UTC+1. This message proves that I, AzizLeBG is in control of the funds and the address as of this time to facilitate the transaction between XX and XX on 2024-08-23."

You should be clear on the purpose of the message, and the timestamp to ensure that no one else would be able to reuse your signed message for other purposes. Bitcoin Signature for Proof of Funds is way too generic and can easily be reused.
As for the verification part, since I'm acting as third party verification, Verifying should not be of any trouble as well? Still doable on Electrum. In this part, I would need an address, a signature and the exact message. The valid signature pop up should clear any concerns regarding ownership.
No, but you should understand that having a signed message doesn't necessarily mean that they would send you the funds in the future. ie. I can borrow 2BTC from someone else, sign the message and send them back. This doesn't guarantee that they would commit to the transaction.

Perfect, thank you all! I learned a lot.

So Electrum is my best option in this case? It has a built in feature and is a pretty old and known wallet. Also, as always in a safe environment.
Electrum or Bitcoin Core are probably two of the most well known and developed wallet. If you're sure that you can operate your wallet in an environment that is safe and secure, there shouldn't be any problems whatsoever that concerns security.

Your idea for signing message should primarily be proving the ownership of the address. Signing a message will prove that they are in ownership of the address and whatever amount of Bitcoins associated with that address at that point in time. You should be clear about the message and the context, specifically taking note of the purpose and the timestamp within the signed message.

I appreciate your thoughts, What should be an ideal message example? Something like this maybe? Do take into consideration that I'm the one to request it and verify it. Nobody else involded.
 
Message: "Bitcoin Signature for Proof of funds "
Signature: H5g/Jc...<...>...P6Ty5=
Timestamp: 2024-08-22 15:00:00

As for the verification part, since I'm acting as third party verification, Verifying should not be of any trouble as well? Still doable on Electrum. In this part, I would need an address, a signature and the exact message. The valid signature pop up should clear any concerns regarding ownership.

Signing a message is pretty much like signing a transaction. The only difference is that the digest is computed by hashing the message string (after prepending a fixed value to the start of it) instead of the transaction. Hash algorithm and ECDSA and subsequently the ephemeral key (k) selection are all the same.

So if the software that is used for signing transactions (sending bitcoin) is secure, the result for message signing should be safe as well. Otherwise singing a transaction would also put you at risk of leaking your key.
And like always use popular open source software that is extensively reviewed and is bug free.

So Electrum is my best option in this case? It has a built in feature and a pretty old and known wallet.

Hi,

I'm currently in the transaction facilitation industry, and I was looking to fill an order of a buyer of mine. One of the prerequisites of the transaction is to ask for a Signature Message proving the other party owns their BTC Coins. Now, I have been surfing threw multiples forums of people arguing over this topic. Some say it is 100% safe, if you don't sign using the same K Nonce, do it offline or do it on exchanges, some say there are risks involved.  I find myself in between trying to have a clear idea of this known process in the BTC ecosystem, it's just a really niche feature not really used a lot nowadays.

Any ideas, arguments, or info is appreciated.

Yours truely,

Pure math is reasoning
What do you know about math?  if you know how to solve a key by using pure math,  then this is for you if you know things.
We have 4 points and 4 scalar, 3 points are unknown but they do relate to all 4 scalar keys. Can you point out a hint as to how we can solve any of the 3 points?

Here are our 3 points
Code:
P1=
03f4bef7834ec36e40f1c007a4c27c2f7d2ded709fda3333fdd5801625736ed152
P2=
03389523df912b20e7f5b2223f50a3e074551d3859487701d9e6297b950c9a78ea
P3=
032b0d9abd02f210631ca0fdf138a19c6725f6b67f2dba6c22bf181c73e81abd08
Here are 4 scalar
Code:
A1=
0x1c16e0f93f27c98dfa5
A2=
0x3f6feeff01e9e8d265
A3=
0x181fe2094f092b00d40
A4=
0x200ddfe92f46681b20a
P1+P2= A4, P2-P1= P3, P3-A4= P2*2, P1-A4/2= P3/2.
Here is the trick, A1, A2 and A3 point to different public keys,  however if we subtract A1-1 from P1, subtract A2-1 from P2 and add the results,  we would get 2, which means P1 and P2 are close they are also close to P3 because half of A4 subtracted from P1 equals half of P3.  This is pure math,  but how can we solve any of the 3 points while we only have A4 and why A1, A2 and A3 behave similar to our 3 points?  They are in close range with each other but where are they exactly?

It seems you're dealing with elliptic curve cryptography (ECC) where you have points on a curve and scalar multiplication operations. From your provided information, you have points P1, P2, and P3, as well as scalars A1, A2, A3, and A4.

Your hint suggests that A1, A2, and A3 are related to P1, P2, and P3 respectively, in a way that when you subtract 1 from each scalar and subtract that from its corresponding point, adding the results gives you 2. This indicates that P1, P2, and P3 are likely related to A1-1, A2-1, and A3-1 respectively in some manner.

The relationship between P1, P2, and P3 is also given in terms of scalar operations involving A4. From the relationships provided:

P1 + P2 = A4:

If you add point P1 and point P2 together on the elliptic curve, you get the point A4.
P2 - P1 = P3:

If you subtract point P1 from point P2 on the elliptic curve, you get the point P3.
P3 - A4 = 2P2:

If you subtract point A4 from point P3 on the elliptic curve, you get twice the value of point P2.
P1 - (A4 / 2) = (P3 / 2):

If you subtract half of the value of A4 from point P1 on the elliptic curve, you get half of point P3.
 
Given only A4 and these relationships, it's possible to find the coordinates of at least one of the points P1, P2, or P3 by performing scalar operations with A4.

To find the exact coordinates of the points P1, P2, and P3, you can use scalar multiplication operations on a known base point on the elliptic curve, which is usually provided in ECC. By performing scalar multiplication operations with A4 and using the provided relationships, you can compute the coordinates of at least one of the points. Once you have the coordinates of one point, you can use the relationships between the points to deduce the coordinates of the others.
