Wall Street money is seriously starting to flow back into Bitcoin. On Monday, the U.S. spot BTC ETF saw a single-day net inflow of: $999M, nearly $1 billion! This is the largest single-day inflow since October 6, 2025, when BTC hit its all-time high of $126K. What’s even more noteworthy is— From 2026 until now, the cumulative annual fund flow for Bitcoin ETFs was still around: -$450M But in just one day, it surged by nearly: +$1 BILLION. This isn’t retail investors throwing in a few hundred or thousand dollars to chase the rally. This is billion-dollar-level spot demand re-entering the market through ETFs. And the timing is absolutely critical: BTC just broke out → market structure strengthened → ETF immediately saw its largest single-day inflow in nearly a year. Price moves first, and now the money is catching up. If ETFs can turn this "one-day explosion" into several consecutive weeks of net inflows, that’s the signal I’m really looking for. Because the scariest part of a bull market isn’t a single-day 10% pump. It’s when— The higher the price goes, the more money from the sidelines wants to come in. $1 BILLION IN ONE DAY. Wall Street is buying back into Bitcoin. ₿
