If you want to make the leap into crypto, you need a trusted fiat-to-crypto exchange to convert your dollars into Bitcoin, Ethereum, and other popular tokens. The overall best exchange to use today is Best Wallet thanks to its low fees, seamless mobile experience, and outstanding security.

That said, there are many other great exchanges to choose from, and it’s worth taking a closer look to decide which is right for you. We evaluated over 50 crypto platforms, basing our methodology on their supported fiat currencies, payment methods, security, ease of use, and features. In this guide, we’ll review the 10 best fiat-to-crypto exchanges for 2025 that made the cut and help you choose the one to use for buying crypto today.

The Best Fiat-to-Crypto Exchanges Reviewed

Now let’s take a closer look at each of the top fiat-to-crypto exchanges.

1. Best Wallet – Best for Seamless & Secure Crypto Purchases on Mobile

Best Wallet is our overall favorite fiat-to-crypto exchange and the top pick by far for anyone seeking to buy crypto on a mobile device. This platform offers a free crypto wallet and one-tap exchange for iOS and Android, and the user experience is truly flawless. It takes seconds to sign up and buy crypto, and there’s no Know Your Customer (KYC) check required. So, you can buy crypto completely anonymously.

Best Wallet supports hundreds of fiat currencies and thousands of tokens across 60+ blockchains, so you can buy whatever crypto you want straight from fiat. The exchange uses the aggregator Onramper to automatically find you the lowest fee and the best exchange rate every time, ensuring you get the most tokens for your money.

The other great thing about Best Wallet is that tokens are deposited automatically into a full self-custody crypto wallet. You don’t have to worry that your exchange controls your tokens. Best Wallet boasts cutting-edge security features and has never been hacked, so you can feel confident keeping your crypto in this wallet.

2. Binance – Best for Buying and Staking Crypto

Binance is the world’s largest crypto exchange, so it’s no surprise that it offers a wide range of options for buying crypto. You can purchase more than 300 tokens through the exchange’s one-click buy portal and use any of 35 different fiat currencies, including USD, GBP, EUR, CAD, AUD, JPY, and more. Binance also supports P2P crypto purchases and spot trading with bank deposits.

Binance doesn’t offer the lowest fees or the best experience for buying crypto, but it really stands out if you plan to stake your crypto to earn yield from your tokens. Binance has more options than virtually any other major fiat-to-crypto exchange for putting your coins to work. You can stake more than 300 tokens or boost your yield on coins like BTC and ETH with advanced dual investment strategies.

Binance is also the place to buy crypto if you’re looking for a niche token that’s not widely available. There’s a good chance you can get it on Binance, although you may need to first buy USDT or another major crypto and then swap it using Binance’s main exchange.

3. OKX – Best for Peer-to-Peer Crypto Buys

OKX is one of the top fiat-to-crypto exchanges if you’re interested in buying directly from another crypto holder—a process known as peer-to-peer (P2P) trading. This leading P2P crypto exchange lets you buy more than 100 popular cryptocurrencies using dozens of fiat currencies and a wide range of payment methods. Most major banks are supported, as are instant payment methods like Perfect Money, Skrill, and Zelle.

Crucially, OKX charges no fees for P2P crypto purchases. It also doesn’t require ID verification for small purchases—you can filter the list of results according to which trades don’t entail a KYC check.

Of course, OKX also has an instant buy feature and a spot exchange, so you have even more options to buy crypto from this exchange. The instant buy feature supports credit and debit cards and more than 100 popular cryptocurrencies.

Visit OKX

4. MEXC – Best for Low-Cost Instant Crypto Purchases

MEXC is another great fiat-to-crypto exchange that supports a wide range of payment methods and the most popular tokens, including BTC, ETH, SOL, and stablecoins like USDT and USDC. The range of tokens you can buy with one click is more limited than other exchanges, but MEXC offers ultra-cheap swaps once you have crypto, so this isn’t a big deal for most people.

Our favorite thing about MEXC is how affordable it is to buy crypto using the exchange’s one-click buy feature. You’ll pay less than 4% in fees to convert USD to USDT using a credit or debit card. The fee is less than 3% if you pay with a SEPA bank transfer. That’s pretty inexpensive for buying crypto—and that’s before you consider MEXC’s bonus cash offers for new customers.

You can also buy crypto on MEXC’s spot market for even lower fees, and the selection here includes more than 2,000 cryptos. However, the interface is a bit more complex, and you’ll have to deposit EUR or BRL. MEXC also requires KYC checks for most crypto purchases on the spot exchange.

5. Margex – Best for First-time Crypto Buyers

Margex is a user-friendly fiat-to-crypto exchange that makes the purchase process simple for first-time crypto users. You can buy tokens with a credit or debit card, Google Pay, Apple Pay, or a bank transfer. There aren’t as many purchase options as there are at other exchanges—for example, Margex doesn’t support P2P purchases—but that can be a good thing if you just want to hop on and buy crypto.

Margex supports BTC, ETH, USDT, and more than 50 other cryptocurrencies through its one-click buy feature. You’ll pay about 4.3% in fees to buy USDT with USD using a credit card, which is competitive with other major exchanges. Once you buy crypto through Margex, it’s easy to stake it or swap it for hundreds of other tokens.

Another reason we like Margex for beginners is that it has a lot of entry-level guides to buying and using crypto. If you’re not sure what crypto token to purchase or how crypto swaps work, you’ll find detailed explanations at this exchange.

6. BloFin – Best for Crypto Purchase Bonuses

BloFin is best known as one of the top crypto futures trading platforms, but it’s also a great place to consider getting into the crypto market with BTC, ETH, or USDT. That’s because new crypto buyers at Blofin can take advantage of generous bonus offers, like getting up to 5,000 USDT when you join the exchange and meet specific milestones. That’s a lot of free crypto.

However, BloFin won’t be right for everyone. It only supports BTC, ETH, and USDT for instant purchases and requires KYC for all users. In addition, BloFin doesn’t have a P2P marketplace. All major payment methods are supported, including credit/debit cards, Apple Pay, Google Pay, and bank transfers.

Once you have crypto on BFofin, you can easily swap to hundreds of other tokens with low fees. The exchange also supports crypto staking and has a lot of tools for trading, including a copy trading portal and ready-made trading bots.

7. KCEX – Best for Customer Service

KCEX is an under-the-radar crypto exchange that stands out for its exceptional customer support. At this exchange, you can get help 24/7 in dozens of different languages. The support team is responsive and knowledgeable, which makes a big difference if you have questions and need them resolved immediately.

KCEX enables you to purchase more than 1,000 different tokens using the exchange’s spot trading platform. There’s no instant buy option or P2P exchange, however, and only bank transfers are accepted for deposits. In addition, all customers at KCEX must undergo a KYC check before making a purchase.

The exchange offers a number of opportunities to earn free USDT and offers zero fees for spot trading any of the available tokens. Withdrawals are also free, making this an attractive exchange for users who just need to convert fiat to crypto and then want to move to their own wallet.

8. Bitunix – Best for Buying Stablecoins

Bitunix is a popular fiat-to-crypto exchange that keeps the purchase process simple. It supports credit and debit card payments for BTC, ETH, USDT, and USDC with low fees, making this platform a good choice if you want to convert fiat into stablecoins.

Other payment methods and tokens are available, but only through third-party partners like MoonPay and Simplex. These purchases tend to have higher fees compared to making instant purchases at other exchanges. Alternatively, Bitunix also has a P2P exchange that supports dozens of different banks and e-wallets.

Once you own crypto on Bitunix, it’s easy to stake it or trade it for hundreds of other tokens. Bitunix also offers access to airdrops and bonuses that can help you earn free crypto.

9. Bybit – Best for Large Crypto Purchases

Bybit is our top pick for anyone looking to convert a large amount of fiat into cryptocurrency. There are a few reasons for this, including Bybit’s overall trustworthiness and its support for a wide range of payment options. But the key factor that sets Bybit apart is that it offers 10% off conversion fees for any purchase over $1,500.

That’s extremely good considering Bybit already charges very competitive fees for purchases of widely used tokens like USDT. You can buy USDT with a credit or debit card for around 5.5%. Bybit also supports Apple Pay, Google Pay, and bank transfers.

Other crypto purchase options at Bybit include a P2P exchange and a block trading desk, where you can place extremely large orders and have them fulfilled by a dedicated agent at the exchange. Bybit also supports recurring buys with an auto-invest feature, which is a big plus if you’re looking to increase your exposure to crypto steadily over time.

10. BingX – Best for Fiat Deposits in EUR

BingX is a leading social crypto exchange that offers several ways to purchase popular cryptos. An instant buy feature offers the option to purchase BTC, ETH, and USDT, while a P2P exchange supports more tokens and more payment methods.

We especially like BingX’s fiat deposit option, which is only available for EUR and BRL. This lets you make a deposit to the exchange using a bank account, then trade on BingX’s spot exchange using your balance. In effect, you can directly buy hundreds of different crypto tokens with fees of 0.1% or less.

BingX doesn’t have a recurring buy tool like Bybit, but it does offer crypto staking and a dual investment program to help you earn yield on the tokens you buy. You can also actively trade your tokens through copy trading or using one of BingX’s pre-made trading bots.

What Are Fiat-to-Crypto Exchanges?

Fiat-to-crypto exchanges are crypto exchanges that enable you to convert fiat currencies—like US dollars and Euros—to cryptocurrencies like Bitcoin, Ethereum, and Tether. They are the gateway to the wider world of crypto ownership for many people around the world.

While some of the best-known crypto exchanges are fiat-to-crypto exchanges, it’s important to note that not all are. Many exchanges require users to already own cryptocurrency and deposit it from another exchange or crypto wallet in order to use their platform. Fiat-to-crypto exchanges let you buy crypto if you don’t already have tokens (or buy more if you do).

Most fiat-to-crypto exchanges also enable you to convert cryptocurrency back to fiat, essentially cashing out your tokens. However, this isn’t always the case, and it’s important to check whether a platform is also a crypto-to-fiat exchange if you plan to sell your tokens in the future.

Types of Fiat-to-Crypto Exchanges

There are several different types of fiat-to-crypto exchanges, each of which has its own benefits and drawbacks. We’ll explain the types and help you decide which one is right for you.

Centralized Exchanges

Centralized crypto exchanges are the most common type of fiat-to-crypto exchange. Examples include Binance, Bybit, OKX, and many of the other platforms we ranked.

These exchanges are ‘centralized’ in the sense that they act as an intermediary for your transactions. When you buy crypto, for example, you buy it directly from the exchange, not from another crypto owner on the blockchain. When you trade crypto on a centralized exchange, the exchange acts as the counterparty to your trade.

Centralized exchanges are very convenient and user-friendly, and many offer 24/7 customer support. They also have relatively low fees for buying cryptocurrency and support a wide range of payment methods and fiat currencies.

However, it’s important to remember that you’re not fully on-chain when you buy crypto from one of these platforms. Typically, your tokens are held in a custodial wallet that is managed by the exchange. You don’t have access to the wider world of Web3, and you usually can’t transfer your tokens to a self-custody wallet you control without paying a withdrawal fee.

Crypto Wallets With Fiat On-Ramps

Many self-custody crypto wallets also have fiat on-ramps that enable you to buy crypto. For example, Best Wallet lets you buy thousands of cryptocurrencies directly in the wallet app using a variety of payment methods.

These wallet on-ramps can have slightly higher fees than centralized crypto exchanges, although they’re becoming increasingly competitive on price. The benefit is that the tokens you buy are deposited directly in a crypto wallet you control completely. So, you can use your crypto to interact with decentralized apps (dApps) or send it to another wallet without paying withdrawal fees.

P2P Exchanges

P2P crypto exchanges enable you to buy crypto directly from another individual who owns tokens. Typically, the seller sets a range for the amount of tokens they’re willing to sell and the payment methods they’ll accept. You can browse listings for your token and desired payment method, then buy tokens when you find an offer you like.

Many top centralized exchanges, such as OKX, Binance, and MEXC, have built-in P2P crypto exchanges and don’t charge any commissions or fees for using them. So, this can be a cost-effective way to buy crypto. P2P exchanges also support a much wider variety of payment methods and currencies than most instant buy tools.

However, beware of payment scams and make sure you’re getting a good exchange rate based on a token’s current price.

Crypto Derivatives Platforms

Some crypto derivatives platforms, such as crypto futures trading sites, also offer a way to buy crypto. Usually, they work with third-party partners to accept credit and debit cards as well as alternative payment methods such as Apple Pay, Google Pay, and bank transfers.
CoinFutures, to give an example, lets you fund your account with a bank card. Your funds are converted to crypto, and you can withdraw BTC, ETH, USDT, USDC, BNB, or POL.

Does Buying Crypto With Fiat Require KYC Verification?

Buying crypto with fiat may or may not require KYC verification. It all depends on where you’re buying tokens and how much you’re buying.

The best way to buy crypto with no KYC verification is to use a self-custody crypto wallet like Best Wallet. Best Wallet is completely anonymous and lets you buy thousands of tokens with absolutely no verification.

Another option to buy crypto with no KYC is to use P2P exchanges that aren’t run by a centralized exchange (most P2P purchases on centralized exchanges do require KYC). You can also use a Bitcoin ATM, although these are increasingly requiring ID verification.

Most major centralized crypto exchanges do require KYC checks for all customers. However, you can find some no-KYC crypto exchanges that let you buy small amounts of crypto without verification.

How to Use a Fiat-to-Crypto Exchange
