Summary
On October 12, 2026, smaller cryptocurrencies outperformed larger ones, with the CoinDesk 80 index rising about 3% over 24 hours compared to a 1.2% gain for the CoinDesk 5. Bitcoin traded below $83,500, while ether increased around 2.5%. CoinDesk research highlighted that bitcoin and ether order books have recovered since the October 2025 flash crash, but altcoin liquidity has declined. U.S. spot bitcoin ETFs saw $681 million in net outflows last week, the largest since June, ahead of the upcoming U.S. consumer price index data.
Why it matters
The report suggests that market makers focus on major cryptocurrencies due to better liquidity, while thinner trading in altcoins results in more volatility and speculative rallies. The significant outflows from bitcoin spot ETFs indicate reduced institutional interest in the short term, possibly influenced by macroeconomic factors like upcoming inflation data. The thin liquidity in altcoins and increased speculative activity may have implications for market stability and investor behavior.
Key context
This rally occurs one year after the October 10, 2025 flash crash, which disrupted liquidity. Although bitcoin and ether have regained order-book depth to pre-crash levels, altcoins continue to see reduced liquidity. The ongoing outflows from U.S.-listed spot bitcoin ETFs contrast with increased derivatives trading volume, suggesting faster position changes rather than new positions. Notable token movements include Starknet and LayerZero rallies, and Zcash’s price rise despite its connection to a laundering case.
Key numbers and entities
Bitcoin traded below $83,500, ether was around $2,560. The CoinDesk 80 index rose approximately 3%, CoinDesk 5 rose 1.2%. U.S. spot bitcoin ETFs recorded $681 million net outflows last week. Futures 24-hour trading volume hit $126 billion, up 81%, with open interest at $145.8 billion, up 2.44%. Zcash had $5.46 billion in futures volume and a 6% price increase. Starknet rose 76% over the past week, LayerZero gained 21% in 24 hours. Losses from the Ledger attack are estimated between $86 million and $93 million.
What remains unclear
The source does not fully explain the drivers behind altcoin liquidity erosion over the past year. The specific impacts of macroeconomic data, such as Wednesday’s CPI figures, on these trends remain to be seen. The reasons behind the prolonged outflows from ether spot ETFs and the institutional investor sentiment towards bitcoin during this period are not explicitly detailed. Additionally, the long-term consequences of the Ledger supply-chain attack on affected tokens and markets are not established.
