TLDR
Altcoin volume is concentrated on centralized exchanges, with KuCoin capturing a record share recently; DEX flows are strongest on Ethereum (Uniswap) and Solana ecosystems per recent market coverage. See the CoinDesk report.
- Centralized exchange altcoin trading sits near cycle highs even with weak prices per a CryptoQuant analysis.
- KuCoins share rose, with altcoins forming most of its activity per a CoinDesk market update.
- Solana memecoin flow elevated DEX turnover (for example, PumpSwaps record volume) per the CoinDesk 20 update.
Deep Dive
1. CEX Cycle Highs
Altcoin activity on centralized exchanges has reached cycle highs despite depressed prices, indicating active rotation by larger players. A recent overview notes altcoin CEX volume (excluding the top five assets) is significantly above prior cycles, even as many tokens remain down materially, with whales and professional traders driving turnover during thin liquidity windows per a CryptoQuant analysis.
- Retail participation faded after losses, but trading did not vanish; it concentrated among bigger accounts per the analysis above.
- Thin spot depth means smaller orders can move price sharply, so volume leadership matters for execution per a CoinDesk market update.
If you need reliable fills in altcoins, central venues with sustained turnover are safer for sizing and slippage than thin books.
2. KuCoin Share
KuCoins share of centralized exchange volume hit a record in 2025, and altcoins comprised the majority of its trading activity as its growth outpaced broader CEX volumes per a CoinDesk report.
- Volumes exceeded $1.25 trillion, split broadly between spot and derivatives per the report above.
- Elevated baseline activity suggests structurally higher user engagement beyond short-lived spikes per the same update.
For altcoin breadth (listings beyond BTC/ETH), venues increasing market share and running balanced spot/derivatives flows tend to be key liquidity hubs.
3. DEX Hotspots
On-chain altcoin flows are strongest where memecoin and DeFi activity are concentrated, notably Ethereum and Solana. Early January saw memecoin trading jump to 41% of altcoin exchange activity, with Solana-focused trading highlighted (for example, PumpSwaps record $1.2 billion volume) per a CoinDesk 20 update.
- Sector rotation shows memecoin share expanding while privacy coin turnover fell, shifting where DEX liquidity sits per a CoinDesk indices piece.
- Liquidity pockets often cluster around leading DEX routers and per-chain hotspots during narrative surges per the updates above.
If you prefer on-chain altcoin exposure, monitor venues tied to current narratives (Ethereum/Uniswap and Solanas main DEXs) for depth, spreads, and pool concentration.
Conclusion
Altcoin volume leadership sits with centralized exchanges, with KuCoins rising share a notable recent shift, while DEX activity concentrates where memecoin and DeFi narratives are strongest (Ethereum and Solana). For practical execution, check venue-specific depth and spreads before sizing, and be mindful that low spot liquidity can amplify moves even when headline volume is high.
