Ternio has put out a crypto debit card called BlockCard. It works in the USA and around the world and supports Bitcoin, Ethereum, and Stellar Lummens. The Blockcard comes in a virtual, plastic, and metal version of the card. It works anywhere major credit cards are accepted. You can now earn $10 for you and a friend by inviting them to join.
I created a detailed blog post on how you can earn $10. I do include my referral link if you want to use it, but you're not required to.
