OKEx Currencies and Payment Methods 

OKex allows buying Cryptocurrencies from 40 different countries, using multiple payment methods. This makes it highly flexible for those who want to buy Cryptocurrencies in a secure environment.

During our review, we have found that all payment methods are trustworthy with OKEx and that the quickest method is to buy with Debit/ Credit Cards.

Visa/ Mastercard

If you own a Visa or MasterCard and your country allows buying cryptocurrency, there is good news for you.

You can easily buy 10 of the world’s top-tier cryptocurrencies through Visa and MasterCard. After making the payment, you will receive the Cryptocurrency within a minute.

The available cryptocurrencies for Visa/ Mastercard are- USDT, BTC, ETH, XRP, LTC, OKB, BCH, BSV, USDK, and LINK.

Bank Transfer

Bank Transfer is another way to buy Cryptocurrencies through the OKEx platform. It is suitable for those who want to buy Cryptos at a bigger volume.

However, as the OKEx platform is not available in the US, you will not be able to make payment through bank transfer in US dollars. However, it supports bank transfers from the following currencies- EUR, CNY, ARS, GBP, AUD, etc.


OKEx P2P Trading

P2P trading is a process to buy or sell Cryptocurrencies through a social network within the OKEx platform. Here, if you want to buy any Cryptocurrencies, you should search for sellers. Once the payment method and available Cryptocurrency match your expectation, you can buy them instantly.

Via this method, OKEx will ensure that you will get the Crypto, and in case of discrepancy, you can always open a dispute. 


Third-Party Payment

For third-party payments, OKEx uses some notable platforms, such as- Paxful, Koinal, Xanpool, Coinify, Simplex, BANXA, Indacoin, Mercury, Moonpay, OKCOIN, Latamex, Advcash, and Menapay.

Based on our review of the payment systems, it is clear OKEx uses a variety of payment processors so that investors and traders from all levels can take part Moreover, P2P trading makes exchanging Cryptocurrencies more accessible and flexible. Users can also dispute any discrepancies during the fund transfer to ensure P2P is secure and reliable. We have gone through the dispute process and found it adequate but time-consuming.

OKEx Safety and Security 

OKEx emphasizes security measures to assist users regarding their safety of crypto assets. This platform uses two/ multi-factor authentication that provides strong security measures for the company. Once logged-in, users will receive an authentication code directly to their mobile phone, email address, or authenticator app so that they can remain safe from any anti-phishing activity.

Overall, during our review, we have found OKEx to be a safe cryptocurrency exchange with many security features. Furthermore, this platform did not face any experience of hack or significant security breaches.

OKEx uses cold and hot wallets, and its infrastructure is very secure. We all know that Bitcoin security is based on BTC private key encryption algorithm where BTC experts believe that SHA256 and EDSA are safe, based on current decryption capabilities. However, the main challenge is the safe storage of private keys ensured via a cold wallet.

OKEx has also provided a solution that looks to overcome the Cold Wallet’s technological challenge and focused on Hot Wallets to ensure more safety measurement.


Overall, based on our review, we can say that the OKEx is a secure platform, and your Crypto investment in this platform is highly secure. However, you have to take some precautions while maintaining your Crypto asset to reduce the chance of loss, and a separate hardware wallet remains the safest option. 

OKEx Fees and Limits

OKEx fees are highly competitive where the platform uses a maker-taker model. In this method, when you place an order, you become a maker who has to pay a lower fee. On the other hand, if you take someone else’s trade, you will be a taker. In that case, you have to pay a higher fee.

For the trading fees, OKEx has implemented a dual-tiered fee structure. If you are a high-volume with more than 1K BTC transactions, you will receive a discount from the platform. Moreover, if you make more than 150K BTC transactions per month, you will receive a negative fee from maker traders. Instead of taking charges from them, OKEx pays them to provide liquidity.

On the other hand, traders who hold 40% of OKEx’s proprietary exchange token will enjoy an additional reduction in fees. Furthermore, new traders have to pay 0.1% maker and 0.15% takers fee. We have found the non-spot trading is cheaper where makers should pay 0.02% and takers should pay 0.05%. See the full breakdown of fees here

Based on our review, OKEx has low fees that may encourage traders to take part in it; being lower than most of its peers. Moreover, on spot trading, the spread depends on the difference between the bid price and the asking price, where the higher liquidity ensures a lower spread for OKEx.

OKEx Verdict

Editorial Team:

OKEx has grown since 2014 into one of the big Crypto exchanges and it is not surprising with such a wide range of services offered, diverse coin selection, and low fees vs its peers. The big miss is with no service available to the US though and their plans for expansion internationally should include this market if they are to continue their growth. Reports of mixed customer service levels are one to take note of, but the offering from the platform itself and its choice of deposit/withdrawal methods give both beginners and advanced traders the features they need; making OKEx a strong choice to start your Crypto journey.
