Bitcoin ETFs See Biggest Day Since May; BlackRock Dominates

The concentration of inflows in a single issuer is the real story here, not the headline number. It suggests ETF demand for Bitcoin exposure is still being expressed through the largest, most liquid vehicle rather than spread across the category, which matters for how the market absorbs future flows. The simultaneous activity in altcoin funds hints that appetite is broadening beyond Bitcoin, though the scale of that shift is unclear. Whether BlackRock's dominance persists on strong inflow days, or the flows start to spread, is the open question.
