Yesterday someone really taken big risk and transferred his money to other wallet dont know who can do it or its legal money transfer or not
here is its blockchain track link https://www.blockchain.com/en/btc/address/12YygZpCEC8VED2oSMQdWCq5xBnHo9ts1Z

what u think how many times he rechecked his btc id and is it legal transaction money used for legal use or some fishy thing !
