I will enounce the perfect crypto card features:

• It's directly connected to your bank account as a debit card, spending fiat money - not only crypto. 
• It has a wide adoption, such as Visa or Mastercard, and it's virtual - so, stored on your phone. No plastic is needed.
• It has 0% fees and at least a reasonable maintenance cost.
• It rewards you in crypto at the step of 1-2% in ETH, BTC, ALGO or LINK for every purchase. You can hold the rewards or spend them. 

Does anyone have a perfect crypto card? Please comment - I'm listening!
