KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

Silver nears $1 billion in volume on Hyperliquid as bitcoin remains frozen: Asia Morning Briefing
Silver perps have more volume on Hyperliquid than SOL or XRP.
What to know:
- Silver futures on the Hyperliquid crypto derivatives exchange have surged to become one of its most active markets, ranking just behind bitcoin and ether in trading volume.
- The SILVER-USDC contract’s high volume, sizable open interest and slightly negative funding suggest traders are using crypto infrastructure for volatility and hedging in macro commodities rather than for directional crypto bets.
- Bitcoin is holding near $88,000 in a "defensive equilibrium" with cooling ETF inflows, uneven derivatives positioning and rising demand for downside protection, while ether lags and capital rotates toward hard assets like gold and silver.
