COSS 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 COSS consists of four parts: general information, fees, deposit methods and security.

General Information

COSS is a cryptocurrency exchange based in Singapore. Singapore is one of Asia’s biggest birth givers to cryptocurrency exchanges. There are SO many.

COSS promotes five factors as the main benefits of its trading platform. These five factors are transparency, instant conversion, state of the art security, integrated cash flow and “FSA”. FSA stands for the fact that 50% of all trading fees that the exchange charges goes back to the holders of the exchange’s own token, the COS-token.

COSS Advantages


COSS does not list US-investors as prohibited from trading, but US-investors should do their own independent assessment of any problems arising from their residency or citizenship. In a worst-case scenario, they may not be able to trade at one or several exchanges that would otherwise have been the best cryptocurrency exchange site for them (maybe including this one).

COSS Trading View

Different exchanges have different trading views. And there is no “this overview is the best”-view. You should yourself determine which trading view that suits you the best. What the views normally have in common is that they all show the order book or at least part of the order book, a price chart of the chosen cryptocurrency and order history. They normally also have buy and sell-boxes. Before you choose an exchange, try to have a look at the trading view so that you can ascertain that it feels right to you. The below is a picture of the trading view at COSS:

COSS Trading fees

Fees are important. There is no way around that fact.

This particular exchange doesn’t charge different fees between takers and makers. Their fee model is instead something called a “flat fee model”. For investors who prefer to pick-up existing orders from the order book, this might be an attractive trading fee model.

This trading platform’s flat trading fee is 0.20%. This is actually slightly below industry average (global industry average can be argued to be approx. 0.25%).

COSS Withdrawal fees

COSS charges a withdrawal fee of 0.001 BTC when you withdraw BTC. This is also in line with industry average.

Deposit Methods

COSS does not accept any other deposit method than cryptocurrencies, so new crypto investors are actually restricted from trading here. If you don’t have any crypto but want to start trading at this cryptocurrency exchange site, you will first have to purchase cryptocurrencies from another exchange site and then, as a second step, deposit them here.

COSS Security

This trading venue’s security score is C+, when performing the test at Observatory by Mozilla ( This is also in line with industry average when it comes to top crypto exchanges.


Finally, the exchange reviewed above has a large number of supported cryptocurrencies. If a large number of supported cryptocurrencies is an important factor for you in your choice of cryptocurrency exchange, you could also check out the following exchanges:

  1. Changelly
  2. Bleutrade
  3. YoBit
  5. KuCoin
  6. BTC-Alpha
  7. Trade Satoshi
  8. Nova Exchange
  9. OKEX
  10. Exrates
