This Tuesday, the US Bitcoin spot ETF experienced a long-awaited influx of funds. The single-day net inflow reached $753.7 million — the strongest in nearly three months.

Looking at the specific numbers shows how hot the market is: a total of $753.7 million flowed into 12 Bitcoin spot ETFs across the US, the highest single-day performance since October 7 of last year. Among them, Fidelity's FBTC led with $351 million; Bitwise's BITB followed closely with $159 million; and BlackRock's IBIT also garnered $126 million. The numbers speak for themselves, making the capital flow clear.

What does this reflect? Nick Ruck, Research Director at LVRG Research, believes that institutional investor demand has fully rebounded. After last year's cautious and risk-averse period, they are now actively deploying capital again. In simple terms, the "silver bullet" for institutions has returned.

Even more interestingly, this wave of enthusiasm has spilled over into Ethereum. The Ethereum spot ETF also received a net inflow of $130 million on the same day. The confidence in the entire cryptocurrency market is warming up, which is a clear signal.

Why did the funds choose this timing to enter en masse? Vincent Liu, Chief Investment Officer at the well-known quantitative trading firm Kronos Research, shared his view: the overall economic outlook has become clearer, giving investors more confidence and courage to make decisions.
