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,
