I have experienced such fake exchange withdrawal requests many times from unknown users on telegram. They always have some same first sentence like.
Hello, I got some XX amount of fund on an exchange and can you help me in withdrawing those. I would give you a XX% as an reward out of it.
This is most probably a scam attempt and I just go with blocking the ID and reporting it as a spam mostly.
But yaa thats a pretty stupid trick to scam anyone, excited to know how much do the Spammer earn from this trick. I would guess not much.
