It’s not your information that you’re going to provide, but the information of the sender. If it’s coming from your account in another wallet, you can fill in your name.
No, there is no file upload option, but I don’t want to fill in wrong information, as it could have serious repercussions in the future.
I am a bit confused on that point. Am I not the sender when the deal is going from my account? And you haven't cleared the KYC verification of the platform. Have you already verified your account with them? Then your information is already with them, and they could automatically track your information from their data. I am actually not getting what you mean by 'sender'. Do you mean when you are going to buy Bitcoin, then you need to provide the sender name? If so, then how will you know the real sender name?
If you are the sender, meaning you are selling Bitcoin, then the exchange should already have your information. It doesn't ask for every exchange; they should store your information once it has been provided. I am not familiar with this kind of local exchange in my country. I am used to Binance or Bybit P2P exchange, which is pretty easy.
