CoinEx, the Seychelles-based cryptocurrency exchange founded in December 2017, announced on September 15 that it will permanently cease operations, citing a prolonged market downturn, collapsing trading volumes, and compliance costs that the exchange described in its official statement as exceeding "reasonable boundaries." All user withdrawals must be completed by December 22, 2026 at 02:00 UTC. After that date, unclaimed funds denominated in USDT will be held in custody at a 5% monthly fee, with a final claims deadline of August 22, 2028.

The shutdown proceeds on a firm schedule. New user registrations were halted on September 15, and futures positions moved to reduce-only mode. All non-spot services, including margin trading, fiat transactions, lending, staking, and on-chain deposits, will cease on September 22. Spot trading ends September 29, which is also the deadline for users to participate in a repurchase of CoinEx's native CET token at 0.005 USDT per token. CoinEx says its reserve ratio exceeds 100%, meaning all user balances are fully backed. The exchange's wallet and vault products are not affected by the shutdown.

CoinEx's path to closure was shaped by two significant events in recent years. In September 2023, the exchange suffered a hot wallet breach attributed to North Korea's Lazarus Group via a leaked private key, with losses estimated between $54 million and $70 million; CoinEx pledged full user restitution following the incident. Then in June 2026, CoinEx discontinued services to users in the European Economic Area after a Wall Street Journal report flagged $3.84 billion in Iran-linked transaction flows, a characterisation the exchange disputed.

Founder Haipo Yang, who previously built ViaBTC into one of the largest Bitcoin mining pools in the world, framed the decision in financial terms. "Revenues can decline, responsibility does not," he wrote in the wind-down announcement. "Carrying unlimited risk for limited revenue is no longer a rational choice." The exchange's official statement cited "Prolonged market downturn, weaker industry trading activity and liquidity, and rising regulatory and compliance costs that exceeded reasonable boundaries" as the primary drivers. The numbers bear that out at a sector level. Global spot trading volume fell to roughly $679 billion in April 2026, down approximately 73% from a late-2024 peak of around $2.6 trillion per month. Average daily volumes across all exchanges have dropped roughly 50% since December 2025.

CET's market data underscores how far the exchange had already fallen before today's announcement. The token trades at approximately $0.005, against an all-time high of $0.1503, giving it a market capitalization of around $12.2 million and a CoinGecko ranking of 1,094. Trading volume in CET jumped roughly 337% on the announcement day, consistent with withdrawal-driven activity, per analysts. The buyback price of 0.005 USDT is effectively the floor, offering CET holders little upside.

The closure lands hardest on users in markets where CoinEx served as a practical substitute for exchanges that have restricted or never operated locally. The platform supported more than 1,300 cryptocurrencies and over 1,900 trading pairs across 200-plus countries, with explicit support confirmed for Nigeria, Kenya, India, Pakistan, South Africa, and the UAE. In these regions, CoinEx attracted users with multilingual interfaces covering 18 languages, low minimum requirements, and payment options tailored to local banking infrastructure. Larger exchanges, including Binance and Coinbase, have periodically suspended or limited services in several of these markets, leaving mid-tier platforms as the primary on-ramp. The practical risk for affected users is threefold: some retail participants in these regions may not see the announcement before the December deadline; holders of less liquid altcoins need to act before September 29, when spot trading ends and remaining non-USDT balances will be converted automatically; and CoinEx has specifically warned that any communications issued in its name after the wind-down begins should be treated as fraud, a warning particularly relevant in markets where crypto scams spread rapidly through social media.

Users displaced by the closure have options, though none replicate CoinEx's breadth of altcoin access. In Nigeria, Yellow Card and Quidax offer naira-denominated trading and local bank integration. In South Africa, VALR is FSCA-licensed under CASP Category I and II. Luno remains active across parts of East and Southern Africa. In India, CoinDCX and WazirX are SEBI-registered, and OKX and Bybit both maintain regional operations across South Asia. Binance P2P and Bybit P2P continue to serve as workarounds in jurisdictions where full fiat onboarding remains restricted.

CoinEx is not closing alone. AscendEX announced closure on July 11, 2026, after failing to secure a MiCA licence and losing a key liquidity partner. BitMart began a phased shutdown on July 26. BitMEX announced it will close permanently on September 23, ending 11 years of operations. More than 99 crypto projects had already folded by July 2026, according to tracking by RootData. The pattern points to structural pressure rather than isolated failures. As volume concentrates among the top six exchanges (which now control more than 60% of all activity), compliance costs, fee compression, and the difficulty of maintaining deep liquidity in a shrinking market are eliminating the conditions that once allowed smaller, generalist platforms to survive. For users in markets that the largest exchanges treat as secondary priorities, that consolidation leaves fewer viable alternatives, not more.
