By the looks of it, looks like that address does not have any previous transaction history. It looks like nobody owns it.
This really isn't necessarily true. Many exchanges have unique addresses for each customer, so having no transaction history is 100% normal. Besides, he didn't just pick a random address to sent the coins to. He was going to send USDPax and he knows that this is a USDT address, so the address is most likely owned by a service he uses.
Another option would be to request help from PAX, since they can simply issue new tokens for you. But the chance they're going to help you is also small.
0% chance of this happening. What are they going to do? Just give him free USDPax and let the ones in the address alone? Or block the ones in the address and re-issue them to OP?
Case 1:
- I send 100 USDPax to my exchange, trade to BTC and withdrawal.
- "Oh, I used the wrong address, please give me the 100 USD back"
- They block the exchange's 100 USD and give me 100. Now I have $200.
Case 2:
- I send 100 USDPax to my other address.
- "Oh, I used the wrong address, please give me the 100 USD back"
- They just give me 100 USD. Now I have $200.
