尽管比特币在盘外市场上处于领先地位，但比特币周末的流动性已经消失，因为机构在工作日占据主导地位

Bitcoin still trades 24/7, but the market behind that price is no longer equally resilient at all hours. As institutional money has concentrated around weekday US sessions, weekends are increasingly where thinner liquidity, wider gaps, and sharper dislocations first show up. Bitcoin might trade around the clock, but its liquidity doesn't anymore. The asset that was supposed to become more resilient after absorbing billions in institutional capital through ETFs has instead developed a split personality, one that looks deep and orderly during New York trading hours and considerably more fragile once Wall Street's desks go dark. Fresh data from Kaiko published this week quantifies what many traders have felt for a while: the same ETF-driven maturation that deepened Bitcoin's weekday market has hollowed out its weekend trading , creating a two-tier trading environment where smaller participants absorb a disproportionate share of risk. Since spot Bitcoin ETFs launched in January 2024, institutional participation has concentrated during US weekday sessions, pushing the share of trading volume occurring in those hours to roughly 47%, according to Kaiko's analysis. Weekday volumes now consistently run at double weekend levels, a gap that has widened throughout 2025 and into 2026 as institutional allocations have grown. The promise of a uniform 24/7 market, the feature that was supposed to distinguish crypto from everything else in finance, is weakening in practice because Bitcoin is still open every Saturday and Sunday, while the capital that provides its depth isn't. Why this matters Bitcoin’s market is starting to behave less like a uniform 24/7 asset and more like a split system, with institutional depth during the week and weaker protection on weekends. That matters because retail traders are more likely to be active when liquidity is thinner, making sharp moves, bad fills, and liquidation cascades more likely when market stress hits.
