The broader altcoin market has noticeably outpaced the largest cryptocurrencies. The CoinDesk 80 index has gained about 3% over the past 24 hours. Bitcoin, meanwhile, has barely changed and is trading around $84,000.
What the indices show
CoinDesk 5 reflects the performance of the largest cryptocurrencies by market cap. CoinDesk 80 covers the broader altcoin market beyond the top five. Over the past day, the second index has risen more than twice as much as the first. This shows that the main demand has shifted not into the largest coins, but into the second tier of the market.
Why altcoins are rising faster
The main feature of the current move is low trading volumes. In a thin market, the order book becomes less dense. In such a situation, even relatively small purchases can move the price more. Therefore, a gain of a few percent does not necessarily mean the emergence of large, sustained demand.
Why thin liquidity matters
The fewer orders there are in the order book, the higher the likelihood of sharp moves. Spreads can become wider. Slippage on entry and exit also increases. Therefore, a move on low volumes usually requires additional confirmation after full liquidity returns.
What is happening with Bitcoin
Against the backdrop of the altcoin rally, BTC remains around $84,000. At the same time, about $681 million flowed out of spot Bitcoin ETFs over the past week. This means that the institutional flow for the leading cryptocurrency remained negative. In such conditions, part of the short-term capital may move into more volatile coins.
Why BTC is flat while altcoins are moving
When the largest cryptocurrency trades in a narrow range, traders more often look for movement in smaller assets. In a thin market, this effect becomes stronger. But such dynamics can quickly change if large volumes return to Bitcoin or institutional flows intensify.
What's next
The main question is whether altcoins' outperformance will persist after normal liquidity returns. If volumes rise and CoinDesk 80 continues to outpace the largest coins, the move will receive stronger confirmation. If the rally quickly fades, the current momentum will remain mostly an effect of a thin market. Additionally, it is worth watching for new flows into Bitcoin ETFs.
Did you catch this altcoin rally in a thin market?
A 3% move in a day may look attractive, but with low liquidity, the price can reverse just as quickly. For a prop trader, the list of available instruments also matters. Different prop firms have different sets of cryptocurrencies, weekend trading rules, and daily drawdown conditions. These parameters are best checked before opening a position.
