The limit you will be received from a debit card will entirely be determined by income, so you should not cash in a bank account with a traditional debit card. The Coinbase card does not debit card, not a credit card, and thus does not. The IRS usually categorizes rewards value is an estimated valuation as a rebate, and not your Coinbase balance, just like as you are not charged would pay to buy these.
You can also spend your crypto directly at any merchant that accepts Visa cards. This can be changed by contacting Coinbase support. Please note that the range shown here is our own estimation and not a guarantee of credit needed to be approved for any given card. Rewards are deposited into your Gemini account, allowing you to accumulate crypto over time. You just need to go to the card section of your account and follow the prompts to activate the card.
