- CoinEx is shutting down while fully solvent, not because it ran out of money.
- Founder Haipo Yang blames collapsing trading volume and rising compliance costs.
- CET holders will be bought out at the token’s original listing price.
- The closure extends a 2026 pattern of mid-tier exchanges leaving the market.
CoinEx, the nine-year-old exchange built inside Haipo Yang’s ViaBTC group, will stop trading and fully wind down by December 22, 2026, and it is doing so from a position almost no failing exchange ever reaches: solvency. Reserves sit above 100%, withdrawals are open from day one, and every user balance is backed. The case is worth reading not because another exchange died, but because a healthy one decided to, and the reasons its operator gave point straight at a problem facing the entire middle of the exchange market.
Yang did not hide behind the corporate language of the official notice. His own words were blunter: “Carrying unlimited risk for limited revenue is no longer a rational choice.” That sentence is the whole story compressed into nine words.
Dear CoinEx Community,
Today, I am announcing that CoinEx will cease operations and begin an orderly wind-down.
First, what matters most: your assets are safe. CoinEx’s reserve ratio exceeds 100%, and every user asset is fully backed and available for withdrawal. Withdrawals…

A $58-million-a-day exchange in a market that pays only the top five
At the moment it announced closure, CoinEx was handling roughly $58 million in daily volume, which placed it around 33rd among tracked exchanges. Put that number next to what happened to the market above it. According to CoinGecko data, combined spot volume across the top ten centralized exchanges fell from $4.5 trillion in the fourth quarter of 2025 to $2.7 trillion in the first quarter of 2026, then to $1.95 trillion in the second, a cumulative drop of more than 55% in six months. The contraction hit everyone, but it did not hit everyone equally. The top five venues now handle somewhere between two-thirds and four-fifths of all tracked volume depending on the month, with Binance alone accounting for close to 37%.
A venue in 33rd place lives on the scraps of a shrinking pie. Its revenue is a thin slice of trading fees on a volume base that halved. Its costs are not thin, and they do not shrink when volume does.
Why a single hack could erase a decade of CoinEx’s profit
Compliance and security spending behaves like a fixed cost that only moves upward. Licensing across multiple jurisdictions, know-your-customer infrastructure, audits, legal exposure and the standing threat of a breach all cost roughly the same whether an exchange processes $58 million a day or $5 billion. Revenue scales with volume. Risk does not.
That is the trap. One successful hack or one enforcement action in a major jurisdiction can wipe out years of a mid-tier exchange’s profit in an afternoon. The upside of running such a platform in 2026 is a modest fee stream on falling volume. The downside is potentially the entire business plus personal liability for the operator. When Yang calls the risk unlimited and the revenue limited, he is describing an insurance contract that stopped making sense to underwrite.
AscendEX, BitMart and BitMEX walked out the door first
The timing and phrasing echo a sequence that ran through all of 2026. AscendEX shut down on July 1, citing its inability to meet the European Union’s MiCA regime alongside the collapse of a key liquidity partner. BitMart began its own wind-down in late July. BitMEX, one of the oldest derivatives venues in the market, set its own closure for September 23 after more than a decade. After that ABFinance’s closure marked four exchange exits in six weeks. CoinEx now joins them, and the shared vocabulary across all these announcements is the same three words: volume, liquidity, compliance.
CET holders get their 2017 entry price back and nothing for the wait
The exchange will maintain a standing buy order for its native token, CET, at $0.005, with no quantity cap and zero trading fees, through September 29. Any CET left in accounts after that date gets repurchased automatically at the same price, with the proceeds credited in USDT. Yang described $0.005 as CET’s original listing price.
Read the generosity carefully. Setting a floor at the listing price with no cap is more than most collapsing exchanges offer their token holders, and public CET quotes were already sitting near that level after a long decline, so the platform is not lifting anyone far above market. The nominal figure flatters the reality. A holder who bought CET at launch and rode it through nine years gets their initial dollars back and nothing for the time. This is the founder returning belief at face value, which is his framing, and it is a different thing from returning value. Both statements are true at once.
The exchange dies, the mining pool that spawned it lives on
Here is the detail that reframes the entire announcement. Yang is not leaving crypto. ViaBTC, the Bitcoin mining pool he wrote the first code for in 2016, remains one of the largest in the world and has mined more than 5% of every Bitcoin block ever produced. CoinEx Wallet and CoinEx Vault, both explicitly excluded from the wind-down, keep running.
What is being shut is precisely the one unit that carries the worst risk-to-reward profile in the group: a regulated, capital-intensive, low-margin exchange in a market that rewards only scale. The mining pool sells a commodity service with predictable economics. The wallet and vault are lighter to run and lighter to police. The exchange sat in the crossfire of every regulator and every hacker while earning a shrinking cut of a shrinking market. Viewed that way, this is not a founder giving up. It is a founder cutting the limb that no longer pays for itself and keeping the businesses that do.
Move your non-USDT coins before September 29 or the platform sells them for you
Solvency only helps users who act. CoinEx has front-loaded the pain so that the early stages strip out features while the money stays reachable until the end.
Two mechanics deserve attention because they push risk onto slower users. Non-USDT holdings get converted to USDT by the platform from September 29, so anyone wanting to keep a specific coin in its original form has to move it on-chain before then. And any USDT left after December 22 goes into independent custody carrying a fee of 5% of the balance every month. At that rate a stranded balance is largely gone inside two years. The fee is punitive by design. It works less as a revenue scheme than as a forcing mechanism to empty the book, though it lands hardest on the users who miss the deadline.
Yang has said he considered selling CoinEx rather than closing it, and rejected the idea because users had trusted their assets to the platform and, in many cases, to him. That admission carries a second signal worth watching as the contraction continues. If a nine-year-old exchange with a clean balance sheet and a recognizable brand could not find a buyer worth taking, the acquisition value of a tier-2 franchise in this market may already sit near zero, which sets the terms for whichever mid-sized venue contracts next.
