COSS Review: What You Need to Know About This Crypto Exchange

COSS, a crypto exchange and token ecosystem launched in 2017, promised users passive income through token rewards and trading fee sharing. Also known as Coincub Exchange and Swap System, it was once promoted as a platform that gave back a portion of trading fees to COSS token holders. But today, COSS is a ghost of its former self—low volume, minimal updates, and little community activity. If you’re considering using it or holding its token, you need to know what’s real and what’s just noise.

COSS isn’t just another exchange. It tried to combine crypto trading, a native token with fee-sharing mechanics, and a marketplace for digital services. But most of those features never gained traction. While platforms like Binance or MEXC offer real volume, deep liquidity, and active development, COSS has faded into obscurity. Its token, COSS, a utility token meant to unlock trading fee discounts and revenue sharing, trades at a fraction of its peak value with almost no daily movement. There are no recent announcements, no team updates, and no clear roadmap. If you’re looking for an exchange that’s alive and growing, COSS isn’t it.

What’s worse, COSS has been linked to shady marketing tactics—fake social media buzz, inflated user numbers, and promises of passive income that rarely materialized. Many users who bought COSS tokens expecting regular payouts ended up holding worthless assets. This isn’t unique to COSS. Across Southeast Asia, dozens of similar projects have popped up, promised big returns, then vanished. The real lesson? Don’t chase hype. Look for exchanges with transparent teams, verifiable trading volume, and active development. If a platform doesn’t update for months, it’s dead—even if the website still looks shiny.

Below, you’ll find real reviews and deep dives into crypto exchanges that actually matter—some working, some dead, and others outright scams. You’ll see how platforms like Ardor DEX, Saber DEX, and United Exchange stack up. You’ll learn what to avoid, what to watch for, and how to spot a fake exchange before you deposit a single dollar. This isn’t about COSS anymore. It’s about protecting your crypto in a region full of noise and very little substance.
