Ether's liquidity drop left order books thinner than Bitcoin's despite its 70% rally

What happened

Ether's price jumped 70% in the third quarter of 2026, beating Bitcoin's 42% gain over the same stretch, yet Ether's market got thinner rather than deeper even as the token rallied harder than its larger rival.

Confirmed

Global impact / market context

Thinner order books mean fewer standing buy and sell orders, so each trade can move Ether's price more sharply and widen spreads, which means the gap between the best buy and sell prices. That makes Ether costlier to trade and quick to swing, even after its 70% rally.

Analyst inference

Investors paid up for Ether faster than for Bitcoin, but the trading backdrop weakened, suggesting the rally leaned on thin buying rather than deep, steady participation. Thin markets can amplify both gains and losses, so positioning built on the rally carries extra price risk.

Analyst inference

What to watch

1. Ether's third-quarter 2026 gain was 70%, while Bitcoin rose 42%, so the two assets' relative performance can be compared against future quarters to see if Ether keeps outpacing Bitcoin. Confirmed
2. Traders could compare order book depth, which is the value of resting buy and sell orders, for Ether and Bitcoin over coming weeks to judge whether Ether's thinner market persists or deepens. Proposed
3. Because thinner books can magnify price moves, watch whether Ether's price swings get larger than Bitcoin's for the same trading volume, which would indicate fragile market depth. Analyst inference
