OEX Review

A trading cryptocurrency guide must provide reviews of all of the top crypto exchanges out there, so that you can find the best cryptocurrency exchange site for you. This review of OEX consists of four parts: general information, fees, deposit methods and security.

General Information

OEX is a cryptocurrency exchange based in Hong Kong. Many other exchanges also come from Hong Kong, including (but not limited to), the immensely popular KuCoin, Binance, Bit-Z, Gatecoin and BitFlip. KuCoin and Binance are actually two of the biggest cryptocurrency exchanges in the world, so quite a stiff competition for OEX there.

It is a bit difficult to obtain information from OEX on its offering. Presumably, the non-English version of their site is more helpful. With respect to US-investors, we have not been able to ascertain whether they are permitted or not. In any event, US-investors should always check themselves if there are any issues arising from their residency or citizenship.

OEX apparently has users from nearly 50 countries and regions in the world and supports both BTC and TC trading areas. They claim to have a system built from the ground up with performance in mind that delivers ultra-fast responses and order matching times, ensuring that “you never have to wait when submitting orders”.

OEX Fees

OEX Trading fees

The exchange offers a flat trading fee of 0.20%. OEX does accordingly not distinguish between takers and makers. For investors who prefer to pick-up existing orders from the order book, this might be an attractive trading fee model. 0.20% fee is slightly below the industry average. The industry average is arguably around 0.25%.

OEX Withdrawal fees

We have not been able to find the withdrawal fees of this exchange. This is potentially a risk for you as an investor (if the exchange does not inform of the withdrawal fees anywhere, there is a higher risk that they are high). Accordingly, we strongly urge you to make your own analysis of the withdrawal fees at this exchange before depositing any funds there and before concluding that it is the best cryptocurrency exchange site for you.

Deposit Methods

We have not been able to find any information on the deposit methods here. Accordingly, we cannot say whether they offer wire transfer deposits, credit card deposits or only cryptocurrency deposits.

OEX Security

The security score of this exchange is F, when performing the test at Observatory by Mozilla (https://observatory.mozilla.org/). This is below industry average when it comes to top crypto exchanges.


Liquidity is something very important for all exchanges, cryptocurrency exchanges but also regular stock market exchanges. The above exchange does indeed have great liquidity. However, the following 10 cryptocurrency exchanges are also regularly among the cryptocurrency exchanges with the absolutely best liquidity in the world:

  1. Simex
  2. Bit-Z
