Hello.
Is there any credit cards with cashback in cryptocurrency (btc\ltc\eth ...)?
Firstly, i'm not aware of any crypto credit cards. It is so easy for someone applying online for a credit card to fake all his personal details using illegally obtained details of other people that it is simply unfeasible for any company to issue a crypto-based credit card.
I don't know any bitcoin debit card that have rewards points/cashback either. Debit cards in real life usually don't have this either, only credit cards do.
Remember that bitcoin debit cards are essentially an exchange, that issues you a card that you can fund by transferring BTC into it. They therefore need to make money off charging you fees, not giving you cashback rewards.
