Noob friend sent his sats to his Binance app on iPhone to sell them for CLP. He didn't understand anything and sold them for USDt instead of figuring out the "Binance P2P" market where he could sell to Chilean bank accounts. Now he has no idea how to buy back BTC to sell them to me or how to withdraw his USDt in case I can find him a buyer.

He sent me his credentials but the website wants me to authenticate using a registered security key which he has no idea about.

🤦‍♂️
