COSS review: exchange, wallet and cryptocurrency all rolled into one


COSS cryptocurrency exchange – reviews and review

COSS is a cryptocurrency exchange and provider of payment solutions for online stores wishing to accept payments in cryptocurrencies.
Despite the fact that COSS is officially registered in Singapore, a lot says that this exchange has close ties with Romania. For example, most of the project participants are from Romania. In addition, COSS is a member of the Romanian Chamber of Commerce. It is worth noting that at the same time she is a member of the Singapore Association of Cryptocurrencies and Blockchain (ACCESS).
The official launch of the COSS site took place in April 2017 after the successful completion of the ICO. The exchange is still a beta version of the final product, so you should not expect anything outstanding from it.
Most of the user reviews are devoted to ICO COSS, and not to the cryptocurrency exchange site itself. Many of them agree that the project is ‘excellent, but maybe too ambitious.’
It supports more than 30 cryptocurrencies in pairs with Bitcoin and Ethereum.
At the current stage, it does not support margin trading and probably does not plan to add such options in the future.
For unknown reasons, the commission for trading on the site is not indicated. It was experimentally possible to establish that it is about 0.20%, which is the average value for the industry as a whole.
The trading platform itself has a fairly simple and at the same time standard interface. It does not offer advanced technical analysis tools.
Deposit / withdrawal of funds is available only in cryptocurrencies. Although the company offers the possibility of converting fiat as part of a service for sellers, this does not apply to its exchange.


The backbone of the COSS team, which has 12 members, is made up of experienced professionals from Under Development Office, a Romanian company specializing in software development. COSS’s top management is based in Singapore, with branch offices in Bucharest and New York. Doubts may be caused, perhaps, by the fact that only five out of twelve team members on the Linkedin social network indicate their involvement in the project. Doubts are partially dispelled after reading an impressive list of COSS advisers and strategic partners.

How does a multi-currency wallet work

This wallet supports the most common digital currencies, as well as fiat money. It is divided into three groups: hot, warm and cold.

  • Hot – designed for temporary storage of funds. Funds are on this wallet in the process of confirming the transaction by the network.
  • Warm – funds are transferred here after transaction confirmation. Here they are stored for subsequent operations. The security level in this wallet is increased, while its volume has limitations.
  • Cold – designed for permanent storage of funds. Cold wallets are stored on company computers that are not connected to the network. Operations with them are conducted by COSS financial staff.


As the founders of the platform themselves say, the task of is to popularize cryptocurrencies by providing users with easy-to-use cryptographic and network services and products with a clear interface.
