$254M Left in CoinEx Wallets as Five Rivals Take 88% of Market

CoinEx is closing its doors after nine years, and the on-chain footprint it leaves behind tells a different story than the headlines suggest. Nansen data identifies approximately $253.6 million resting in CoinEx-labeled wallets following the shutdown announcement. This residual balance underscores the operational weight founder Haipo Yang is managing as he winds down a platform whose revenue no longer covers the cost of its compliance and security infrastructure.

The broader market structure reveals why that operational weight became unsustainable. In August, the eleven major centralized exchanges tracked by CoinMarketCap processed $4.23 trillion in combined spot and derivatives volume, a 12.3% increase from July. Despite the rise in overall activity, the market’s tilt toward the largest players intensified. Binance, OKX, MEXC, Bybit, and Gate handled roughly 88% of all trading within the cohort. Binance alone recorded a third consecutive month at a record 43.3% share, moving about $1.83 trillion during the period.

Yang acknowledged that CoinEx failed to secure a leading position, leaving the company with obligations that were hard to reconcile with its income. “Revenues can decline, responsibility does not,” he said. “Carrying unlimited risk for limited revenue is no longer a rational choice.” The exchange will halt spot trading on Sept. 29 and end withdrawals on Dec. 22. This exit follows a 2023 settlement with New York authorities, in which CoinEx refunded more than $1.1 million to 4,691 investors and paid over $600,000 in penalties, highlighting the ongoing regulatory expenses the company is now exiting.

The $253.6 million in labeled wallets comprises roughly $134.4 million in Bitcoin and $27.6 million deployed on Aave. While these figures may include operational funds rather than purely customer liabilities, their scale demonstrates the capital tied to the platform’s infrastructure. As users migrate their assets to other venues, the incoming liquidity will flow to platforms that already hold the majority of market share. This dynamic presents a structural contradiction: the liquidation of a mid-tier exchange’s assets appears to feed the very concentration that made its survival difficult.
