But in this case, you’re given cryptocurrency for your purchases. However, keep in mind that each card differs in how they process and award the cryptocurrency for their cardholders.For example, the BlockFi Rewards Visa Signature Credit Card gives cardholders the following:1.5% back in crypto on all eligible purchases3.5% back in crypto rewards during in the first 90 days of card membership2% back in crypto on all eligible purchases over $50,000 of annual spendBut since there are thousands of cryptocurrencies that you can hold, the card actually rewards you with BlockFi Cryptocurrency Rewards Points. Once the points are deposited and the cardholder account is in good standing, BlockFi will let you convert the points into the cryptocurrency of your choice.Conversely, the Gemini Credit Card deposits cryptocurrency directly into your Gemini account every time you swipe your card — giving you instant access to your rewards — rather than having to wait for the monthly statement to cut.So when you’re researching crypto credit cards, be sure to find out what the process is for rewarding cardholders. It may require an additional step or two compared to more traditional credit cards, but it could be worth it if you have interest in cryptocurrency investing.Also keep in mind that not all of these are solely credit cards, as there are several debit cards available such as the Coinbase and Crypto.com debit cards. So if you’re averse to credit cards, you don’t have to miss out on your purchases earning you more crypto for your portfolio.But remember that the crypto cards still function as normal credit cards, so the balances need to be paid off each month or else you’ll have to pay interest or late fees. While you’ll usually buy things and pay off your card in US dollars, some cards allow you to make purchases (and pay off your card) with cryptocurrency that’s in your associated account.Additionally, the cards affect your credit score the same way as a traditional card, and there may be fees attached to using the card such as annual fees or transaction fees. Make sure to check the terms and conditions for each card to understand what rules apply.What to consider with a crypto credit cardHaving a crypto card is a bit more complex than a traditional credit card, so here are a few things to consider before you apply:Taxes: One of the best parts of a crypto card is the ability to earn rewards that have the potential to rise in value, whereas cash back and travel rewards likely lose value due to inflation and devaluation, respectively. However, these rewards are not taxable, whereas if you earn crypto, it’s considered an asset which is taxable if you decide to sell it. So if you plan to earn or sell a substantial amount of cryptocurrency, you may want to consult a tax professional for guidance.Flexibility: Each crypto card has a different portfolio of cryptocurrencies you’re able to earn rewards in. If you want to invest in specific coins, be sure to find out if the card, and the exchange that supports it, will allow you to invest in the coin you want.Benefits: Many crypto cards are bare-boned when it comes to benefits, so if you’re an avid traveler, you may find more value in a travel rewards credit card. Or if you are trying to save money each month on your purchases, a cash back credit card may serve your needs more effectively.Limitations: Because of varying state laws around the county, not every crypto card is available to everyone. So before applying, be sure to check each card’s terms and conditions to see if you live in an eligible state. Additionally, if you’re managing your cryptocurrency account outside of the United States, you may be violating international laws, so the crypto rewards you earn are best handled within the U.S.Crypto cards available nowSome crypto cards are offering a waitlist, but if you’re eager to apply and start earning—the following cards are open for application.Crypto debit cardsCrypto credit cardsSoFi Credit Card: As you spend on the card, you’ll earn SoFi Credit Card reward points that can be redeemed for either Bitcoin or Ethereum.Venmo Credit Card: You can automatically purchase Bitcoin, Ethereum, Litecoin, or Bitcoin Cash with the cash back earned from purchases.Brex Business Card: You can spend your rewards points you earn on the card on either Bitcoin or Ethereum.BlockFi Credit Card: You can choose to earn rewards in a dozen types of crypto, including Bitcoin and Ethereum.Bottom lineThere are only a few types of credit card rewards, but now, cryptocurrency has been added to that list. It’s an exciting innovation in the credit card industry, but similar to nearly every decision you make in regards to your personal finances, make sure that crypto rewards makes sense for you.Additionally, remember that it’s important to always spend responsibly, even if the rewards can potentially increase in value. Credit card debt is never a good idea, and overspending on a credit card could lead to heavy interest charges.Catch up on Select’s in-depth coverage of personal finance, tech and tools, wellness and more, and follow us on Facebook, Instagram and Twitter to stay up to date.Editorial Note: Opinions, analyses, reviews or recommendations expressed in this article are those of the Select editorial staff’s alone, and have not been reviewed, approved or otherwise endorsed by any third party.
