A broad surge in liquidity and renewed institutional interest propelled the crypto market back into growth in Q3 2025, with total capitalization climbing to roughly $4 trillion — the highest level since late 2021 — and average daily trading volume jumping about 44% to $155 billion; while Bitcoin set and revisited record highs, a particular intra-market rotation saw Ethereum and other large-cap altcoins outpace BTC, reducing Bitcoin’s share of dominance to roughly 56.9% by quarter end and underpinning a diversified advance across major exchange order books. The quarter represented the third consecutive rallying period and the second in which significant capital appreciation was driven by fresh liquidity and institutional inflows, with Binance consolidating market share as its own volumes rose roughly 40% to $2.06 billion, near a 40% share of global exchange activity. Traders and portfolio managers noted that order book depth improved for many large-cap tokens even as concentration metrics shifted. Momentum carried into early October but was abruptly interrupted by a severe mid-month liquidation event that erased more than $370 billion in market value within hours, exposing systemic leverage and fragile liquidity conditions. Bitcoin plunged from peaks near $126,000 to lows around $104,000 before staging a partial recovery to roughly $114,500 by late October, while Ethereum briefly slipped below $4,000 and select altcoins, including Solana and Cardano, experienced declines ranging from steep drawdowns to extreme 50–90% moves. The rout was attributed to a combination of overleveraging, abrupt de-risking by institutional desks, and external macro shocks, specifically escalating U.S.-China trade tensions and tariff announcements affecting technology exports. Additionally, mid-October sessions saw combined ETF net outflows that materially amplified selling pressure. Recent reports also tied the panic to a presidential tariff announcement, citing trade tensions as the immediate catalyst. This episode highlighted how institutional maneuvers and macroeconomic shocks can dramatically influence market volatility and trading volumes.
