Earn Opportunity

There’s no better way to earn crypto than by doing something you already do on a daily basis. That is why I love the Metal Pay app. Anytime you send or receive money, you get paid in Metal’s native crypto $MTL. $MTL can be held for a reduction in trading fees, sent to friends as payment, or saved like money in a savings account!
