COSS Exchange Review

Origins and vision

COSS, which stands for Crypto One Stop Solution, began in 2017 after an ICO held in Singapore. Its founders aimed to pull everything under one roof - spot exchange, multi-asset wallet, merchant payment tools and an IEO platform. 

They also introduced the COS token on Ethereum to give holders a share of the platform’s revenue, hoping to drive loyalty and build a community-centric model. It sounded like a strong blueprint for the early days of crypto exchanges.

What the model offered

A big part of COSS’s appeal was its revenue share - 50 percent of trading fees were paid back to COS token holders automatically through smart contracts. To make trading even cheaper, COSS rolled out a second token called CFT, which granted an additional 25 percent discount on fees when used to pay commissions. The exchange supported standard spot trades with market and limit orders across roughly 30 to 40 listed assets. It ran on a taker fee around 0.2 to 0.25 percent, with maker trades set to zero. Withdrawals cost about 0.0004 BTC, matching common benchmarks in the industry.

Pros and cons

Pros

• Truly unique 50 percent revenue share concept for token holders
• Dual-token approach with built-in fee reductions
• Originally bundled merchant services and wallet support alongside trading

Cons

• Today the platform is non-functional, with no reported trading volume
• User complaints include stuck funds after management changes in 2020
• No growth of fiat gateways or serious merchant adoption
• Liquidity collapsed, leaving most order books empty
• Support issues and long withdrawal delays created major trust problems

How it felt to use

In its first few years, COSS drew in traders with light KYC, a clean interface and API support for bots. Weekly fee distributions to COS holders built a sense of community. But after ownership shifts around 2020, the story changed. Many users reported being locked out of withdrawals, with balances flagged for endless audits. As activity dried up, revenue sharing stopped and token utility evaporated. By 2023, independent trackers largely categorized it as dead, with no live order book or functioning services.

Final take

COSS launched with one of the more innovative community-driven models in crypto exchange history. A revenue-share token plus extra fee cuts promised a fair system that rewarded loyal traders. Unfortunately it didn’t last - liquidity dropped off, features stalled, and users faced problems pulling their funds. The platform today is a cautionary tale: a once-promising ecosystem reduced to an inactive shell.

If you’re exploring exchanges that still pay revenue shares or give trading kickbacks, COSS stands more as a lesson than a live option. Its early story shows what ambitious blueprints can look like, but also how quickly things can go wrong without sustained growth and solid operations.
