The Aven Bitcoin Visa Card is the latest unique offering from financial technology company Aven, which has a number of other distinctive products, including the Aven Home Equity Credit Card and the Aven Rewards Card.
This card, issued by Coastal Community Bank, allows holders to access a Bitcoin-backed line of credit of up to $1 million in liquidity — based on how much Bitcoin they deposit into an eligible account — to make purchases, pay off debt and more. Cardholders must deposit their Bitcoin into BitGo, Aven’s Bitcoin custodian, as collateral for their line of credit. The Bitcoin is returned after you close your account and repay any accumulated interest.
Those features make the Aven Bitcoin card stand out from most other credit cards on the market, but they also make it a much less straightforward product that might be difficult for crypto novices to understand.
Here’s what to know about the Aven Bitcoin Visa.
1. It doesn't work like a typical credit card ...
When you apply for a traditional credit card, your credit limit and interest rate are typically determined based on factors like your credit scores and income. But with the Aven Bitcoin card, your credit limit is determined by how much Bitcoin you have in your BitGo account. The card offers credit limits from $1,000 to a truly mind-boggling $1 million. (Credit lines for traditional credit cards tend to top out in the tens of thousands.)
Relatedly, the Aven Bitcoin card determines your interest rate based on what it refers to as your loan-to-value (LTV) ratio and/or borrowing tier. It's unclear from the card's fine print what the difference is between those terms — or whether there is any difference. Multiple efforts by NerdWallet to reach Aven for comment were unsuccessful. But in practice, when you apply for the card and deposit your Bitcoin, you’ll select a borrowing tier: 30%, 50% or 70% of the value of the deposit. Your LTV ratio is based on the borrowing tier you select; the lower your tier and/or LTV is, the lower your APR is.
Aven’s terms note that cardholders can request a credit limit increase at any time, including when the price of Bitcoin increases. You can also request a change to your borrowing tier by contacting the company.
2. ... Or even like other 'crypto' cards
Typically, you'd expect a "crypto credit card" to earn rewards in the form of, well, cryptocurrency. But the Aven Bitcoin Visa offers 2% cash back on all purchases. (Technically, you're earning points that can be redeemed as statement credit — at a value of 1 cent each — toward your balance and minimum payment due.)
You can also redeem points for flights and hotels through Aven’s travel portal.
So while the Aven Bitcoin card is backed by crypto, it doesn't directly earn you any. And while cash back is far less volatile as a rewards currency, it can't "appreciate" in value the way cryptocurrency can. (Of course, crypto values can also go down.)
🤓 Nerdy Tip
Language in Aven’s terms and conditions describes its various cards’ cash-back rates as "promotions.” The company's terms also state that it “may revise or discontinue Points accrual at any time without advance notice.” Although credit cards can adjust their offerings whenever they like, a card's rewards structure is typically an ongoing feature, not a temporary "promotion." It's unclear how long the Aven Bitcoin card will offer its current rewards rate. Again, multiple efforts by NerdWallet to reach Aven for comment were unsuccessful. » MORE: Best cash back credit cards
3. You can refinance debt with the card
The Aven Bitcoin card lets cardholders use their line of credit to refinance existing debt from other credit cards and Bitcoin-backed loans.
To do this, you can transfer over an existing balance to Aven’s fixed-rate, fixed-term repayment plan of up to 10 years, or to an interest-only repayment plan of up to five years. As of May 2026, Aven said interest rates range from 7.99% to 11.99% for fixed and variable rates. That's significantly lower than rates you'll find on general credit cards. By comparison, the average APR charged for credit card accounts that incurred interest was 21.52% as of February 2026, according to the Federal Reserve.
Further, cardholders can also request to cash out and deposit excess Bitcoin that is not needed to support their line of credit into their bank account. You can view excess Bitcoin available for withdrawal in the Aven app. Note that any Bitcoin you deposit must remain in your account for at least seven days before you can withdraw it.
Keep in mind that Aven charges a 1% draw fee for both balance transfers and cash-outs. This is lower than the typical balance transfer fee — most cards charge 3% to 5% of the amount transferred. However, not all balance transfer cards charge a fee, and there are cards, like the popular Citi Simplicity® Card, that offer introductory 0% APR periods during which you’re not charged any interest on your transferred balance.
4. It’s relatively light on fees
The card does not charge an annual fee, membership fee or prepayment fees like some crypto credit cards do. This makes it easy to keep in your wallet.
However, as noted above, Aven does charge a 1% fee on cash-outs and balance transfers. The company also charges a 2% fee on full liquidations, in cases where it needs to pay off outstanding balances from a cardholder who defaults, or if it needs to bring your LTV down to the ratio you initially agreed to. (See info in subhead No. 1.)
5. There’s risk involved
Unlike with traditional credit cards, your credit limit with the Aven Bitcoin Visa — and therefore your buying power — will fluctuate with the value of your Bitcoin. And while you can request changes to your borrowing tier (which, remember, also helps set your APR), it'll require getting in touch with the company and asking directly. That may be easier said than done.
In any case, because the card is offered by a startup fintech, applicants should proceed with caution. Products from such companies are particularly prone to significant changes as they find their place in the market. A traditional credit card from an established bank can offer more predictability.
