Ok after some minutes of conversation on Telegram with OP, i confirm that OP is a scammer trying to motivate you to create an account of a shady fake exchange. He doesn't use BTC official network ''for security reason'' and wants only to do a internal transfer on his fake exchange.
I cannot say that I am surprised...

Its sad to see how people try to abuse with the war situation in Ukraine, there are people fighting every day risking their life and scammers just thinking how to abuse this situation. A big -1 to OP. Let's hope no one fall in this scam.
