The Gemini Credit Card** lets you earn credit card rewards in bitcoin, ether or more than 60 other cryptocurrencies. You'll earn 3% back on dining (on up to $6,000 in annual spend, then 1%), 2% on groceries and 1% on all other purchases. These rewards rates are pretty competitive, and the cryptocurrency rewards selection is the largest available by far. Rewards are earned the instant you make a purchase, meaning you don't have to wait for the end of the month to get a payout. You're even able to move your rewards to your own crypto wallet, which is a major score for flexibility.

We like the BlockFi Rewards Visa® Signature Card for a lot of reasons. First, it offers more than 10 cryptocurrency reward options beyond bitcoin. It also allows you to move your crypto into your own wallet -- a key distinction that will make it attractive to crypto enthusiasts. Previously, the rewards you earned of 1.5% back on every purchase automatically earned interest when held in a linked BlockFi Interest account, but that offer has been ceased by order of the Securities and Exchange Commission. It's unclear if that feature will return in the same form, despite BlockFi's claim that it intends to get its business compliant quickly. The volatility clearly isn't reserved for crypto prices alone -- there is some inherent risk of abrupt changes in crypto products as the legal dust settles.

The Venmo Credit Card is a cash-back rewards card, but you can choose to redeem rewards in crypto -- bitcoin, ethereum, litecoin or bitcoin cash -- at the end of each month. Unlike some other credit cards, there are no transaction fees for converting rewards to cryptocurrency. Venmo automatically assigns your highest cash-back rate to your highest spending categories. You'll earn 3% back on your highest eligible spend category, 2% on the second highest eligible spend category and 1% on all other eligible purchases, so you don't have to strategize your spending to maximize your rewards. The major drawback is that you cannot transfer your crypto from Venmo's custodial platform to an exchange or your own wallet, which may be a dealbreaker for some.

The Upgrade Bitcoin Rewards Visa is a simple crypto credit card -- or perhaps we should say bitcoin card. Though it doesn't offer anything above and beyond other cards, it's a satisfactory alternative if the other options aren't right for you. You'll only earn bitcoin, but it does offer the same rewards rate as BlockFi at 1.5% back on all purchases. You can use the Upgrade Bitcoin Rewards Visa anywhere Visa is accepted, but you cannot move your bitcoin from the custodial Upgrade platform to your own wallet, limiting your "ownership" to price exposure. The only thing you can do with your bitcoin rewards is hold them in the custodial account or sell them to redeem as a statement credit at a time of your choosing. While this is limiting, it's still one of the most straightforward crypto rewards cards publicly available right now.
