Binance has this way of making money and attracting new users. When you register or log in you can claim the link box and you can also share your own link and win other boxes. I have invited 3 friends and I have won $0.45. However, the boxes can contain between 0.1 and 3 BUSD, which is the equivalent of 1 $=1 BUSD. https://app.binance.com/es/my/wallet/account/payment/binancepay/sharecryptoboxes?_dp=Ym5jOi8vYXBwLmJpbmFuY2UuY29tL3dlYnZpZXcvd2Vidmlldz90eXBlPWRlZmF1bHQmbmVlZExvZ2luPWZhbHNlJnVybD1hSFIwY0hNNkx5OTNkM2N1WW1sdVlXNWpaUzVqYjIwdlpYTXZiWGt2ZDJGc2JHVjBMMkZqWTI5MWJuUXZjR0Y1YldWdWRDOWlhVzVoYm1ObGNHRjVMM05vWVhKbFkzSjVjSFJ2WW05NFpYTV9KbkpsWmoxTVNVMUpWRjlEUWpJNU1qbEpOU1p5WldkcGMzUmxjbU5vWVc1dVpXdzlNakE1TXpnd09ERTNOVFU1TXpFME5ETXk=&ref=LIMIT_CB2929I5&registerchannel=209380817559314432
