So it is indeed a Mastercard, plus some extra fees:

  What are the fees associated with using the Bybit Card?

  Here's a breakdown of the fees:

  – Foreign Exchange Fee: 1% (on top of Mastercard's exchange rate)

  – Crypto Conversion Fee: 0.9% (on top of Spot trading fees)

  – Annual Fee: None

  – Dormancy/Inactivity Fee: None

  – Card Cancellation Fee: None

  – Card Issuance/Replacement Fee: None for Bybit Virtual Card; 5 USD/USDT for Bybit Physical Card

  – ATM Withdrawal Fee: 2% (applies after reaching the monthly free ATM withdrawal limit of 100 USD)

The fees are more than acceptable for the service.
