Our Take 

Coinmama is a small cryptocurrency exchange that allows users to sell Bitcoin for fiat currency. It offers a limited number of cryptocurrencies available for purchase, does not allow crypto-to-crypto trading, and charges high fees for buying and selling crypto. Coinmama may appeal to beginners as an easy way to buy crypto, but advanced traders seeking access to crypto trading, low fees, and a larger coin selection will want to look elsewhere.

Coinmama is a cryptocurrency exchange that offers a simple way to buy and sell a few popular cryptocurrencies online. It doesn't allow crypto-to-crypto trading, and it also outsources many of its transactions to a third-party service (Simplex). Coinmama currently only supports nine cryptocurrencies, which is fewer than most exchanges.

Coinmama users can buy Bitcoin and other popular cryptocurrencies using fiat currency. Users can also sell Bitcoin, but other cryptocurrencies must be withdrawn to a digital wallet to sell elsewhere. Coinmama is not a trading platform and does not offer some of the trading tools of other platforms, such as advanced charting, limit and stop orders, or trading on margin.

Investing in cryptocurrencies, Decentralized Finance (DeFi), and other Initial Coin Offerings (ICOs) is highly risky and speculative, and the markets can be extremely volatile. Consult with a qualified professional before making any financial decisions. This article is not a recommendation by The Balance or the writer to invest in cryptocurrencies nor can the accuracy or timeliness of the information be guaranteed. 

Company Overview

Coinmama was founded by Ilan Schuster, Laurence Newman, and Nimrod Gruber in 2013 as a simple way to purchase Bitcoin. It now offers nine popular cryptocurrencies for purchase, as well as the ability to sell Bitcoin back to the exchange. It is currently headquartered in Ramat Gan, Israel.

Coinmama operates in most countries around the world (including 48 U.S. states), but it's not available in certain locations due to regulatory restrictions. Coinmama is not a traditional crypto exchange, as users cannot trade crypto or purchase crypto with trading pairs. Rather, it’s more of a marketplace where users can purchase crypto with fiat currency. That said, Coinmama does allow users to sell Bitcoin back to the exchange for fiat currency, but any other crypto will need to be transferred off the platform to sell.

Cryptocurrencies That Trade on Coinmama

Coinmama offers a very small selection of cryptocurrencies, including Bitcoin (BTC), Bitcoin Cash (BCS), Ethereum (ETH), and Dogecoin (DOGE). There are only nine supported cryptocurrencies on this platform, though they may add more in the future. Here is the complete list: 

Coinmama does not currently support some of the top cryptocurrencies, such as Solana (SOL), Polkadot (DOT), Avalanche (AVAX), or Tether (USDT).

Trading Experience

Coinmama offers a simple trading experience, as users can only buy crypto or sell Bitcoin. You can deposit funds into your Coinmama account using a wire transfer, ACH transfer, or you can deposit Bitcoin from your digital wallet into the Coinmama platform. Users can also purchase crypto in several other ways, including with Google or Apple Pay, or any Mastercard or Visa card.

Coinmama charges additional fees for using a debit or credit card to purchase, as well as Google and Apple Pay.

Users will need to connect a wallet address to store crypto, as Coinmama does not store any user assets on its platform. This may be a hassle to new users, as finding a compatible wallet for your desired crypto may be confusing. Coimama also does not offer advanced charting or limit or spot orders, so advanced traders may be underwhelmed at the trading features available.


Coinmama charges fees for buying and selling, plus additional fees depending on the payment method used. Coinmama fees are based on the TradeBlock XBX (a popular Bitcoin price index) list + 2% markup. In addition, Coinmama charges a fee for each transaction. These fees are much higher than most crypto exchanges.

Here’s a breakdown of Coinmama fees:

Payment Method Coinmama Fee
Bank Account 2% + up to 3.90%
USD Wallet  2% + up to 3.90% 
Debit/Credit Card  2% + up to 3.90% + 5% (10.90% total)
ACH Transfer  2% + up to 3.90% 
Wire Transfer  2% + up to 3.90% 
Crypto Conversion  N/A
Purchases  2% + up to 3.90%
Google/Apple Pay  2% + up to 3.90% + 5% (10.90% total) 
Bitcoin Sales  2% + up to 3.90% 


Standard security features are available on Coinmama, including two-factor authentication (2FA) and encrypted servers. Coinmama also does not store any user crypto assets, and instead, it requires customers to use their own software or hardware wallets. This keeps assets in user custody instead of on a centralized platform.

Here are some details of the security features offered by Coinmama:

  • Two-factor authentication (2FA). Coinmama offers two-factor authentication (2FA) via third-party authentication apps (such as Google Authenticator.)
  • User custody. Coinmama does not store user coins, and it requires connecting a digital wallet for your purchases. This ensures all users can secure their crypto off the Coinmama platform.
  • Biometric access. The Coinmama mobile app (only on Android) allows users to enable biometric access (such as a fingerprint) to further secure the app.

Opening a Coinmama Account

To sign up for a Coinmama account, you will provide an email address and a password. After verifying your email address, you can log in and secure your account with 2FA. This requires scanning a QR code from Coinmama and inputting an expiring six-digit code from your authenticator app.

Before making any purchases (or withdrawals), Coinmama requires user identity verification. This includes providing your name, address, and other personal information, as well as submitting a picture of a government-issued photo ID. You will also need to submit a photo of yourself holding a piece of paper that says “Coinmama” on it. This aligns with modern Know Your Customer (KYC) standards of security in the U.S.

Customer Service

Coinmama offers customers service over the phone (callback only), via email, through live chat, or on social media. Users can call the voicemail service by dialing +1 (650) 600-9939 and leaving a message with a name and phone number. Coinmama customer service will call back to assist. Most crypto exchanges do not offer phone support, so this sets Coinmama apart from many of its competitors.

Users can also get basic support on Twitter. Overall, Coinmama offers more support options than most crypto exchanges.

Customer Satisfaction

Coinmama receives positive customer reviews overall, with users mentioning simple purchase experiences and helpful customer service interactions. Its few complaints call out the long verification approval time, as well as some accounts being deactivated due to identity verification issues (though users were able to withdraw funds with no issue). 

Overall, Coinmama receives better reviews than some competitors, and customer service seems to respond to complaints quickly.

There are no formal rating agencies for cryptocurrency exchanges so users will have to rely on customer reviews to gain insights into the platform experience.

Account Management

Coinmama allows users to buy and sell crypto through its web-based platform and Android mobile app. Users can log in, view crypto holdings, make purchases, and sell Bitcoin if desired. Coinmama does not offer to trade of crypto, and coins are held in a user’s third-party wallet, not on the Coinmama platform.

The Coinmama mobile app offers similar functionality, allowing users to buy crypto and sell Bitcoin. From the mobile app, users can also deposit or withdraw funds, view their holdings, and transfer funds as needed.

How Coinmama Compares to Other Cryptocurrency Companies

Coinmama is a simple marketplace that allows users to buy crypto, though its fees are higher than many other exchanges. It also offers a simple mobile app for managing user accounts and making purchases on the go.

Coinmama only offers nine cryptocurrencies and no crypto-to-crypto trading, limiting the functionality of the platform to simple purchases only. Users can only sell Bitcoin back to the platform as well; those who want to sell other coins will need to move them off Coinmama to sell elsewhere. Here’s how Coinmama compares to another large crypto exchange in the U.S.

Coinmama vs. Gemini

Both Coinmama and Gemini are cryptocurrency exchanges offering a simple way to buy Bitcoin. Both charge higher fees than certain competitors and allow users to purchase crypto directly with fiat currency. 

But while Coinmama is designed as a marketplace to purchase a few select cryptocurrencies, Gemini offers crypto-to-crypto trading capabilities, the ability to earn interest on holdings, and supports over 50 cryptocurrencies total.

Here are a few other differences between Coinmama and Gemini:

  • Gemini offers over 50 cryptos to buy and sell, while Coinmama only supports nine.
  • Coinmama does not store user crypto assets, requiring an offline wallet.
  • Gemini offers institutional investing services, including over-the-counter (OTC) trades.
  • Coinmama provides customer service over the phone, while Gemini does not.

Coinmama offers a simple way for beginners to buy a few popular cryptocurrencies, though its fees are very high. Gemini is a full-service crypto exchange, allowing users to buy, sell, trade, and stake crypto to earn interest. It also appeals to institutional investors with its OTC trade desk and 24/7 support team.

Final Verdict

Coinmama is a simple, centralized cryptocurrency exchange that offers an easy way to buy select crypto, but with high fees. Coinmama does not take custody of user assets, but instead, it requires that users connect a third-party digital wallet to obtain instant custody of their holdings.

Coinmama fees can be up to 10% of the purchase price, depending on the purchase method, which is higher than almost any other crypto exchange on the market. These markups can cost traders a large portion of their investment, and it is advised to shop around other crypto exchanges to find a better price.

Overall, Coinmama is a high-cost option for beginners who want to buy and hold Bitcoin or other popular crypto assets. Coinmama does offer superior customer service, and its mobile app and web-based platform make it easy to buy crypto. Coinmama may work for beginners, but active crypto traders will want to look elsewhere for more trading options.
