$BTC ETFs saw $1.61B inflow over four days while price ran from $65K to $76.9K — institutions didn't chase, they front-ran.

BlackRock's IBIT accounted for 83% of the final day's inflow alone. That's not retail FOMO, that's size positioning early.

Cycle read: When big money shows up before breakout momentum, it signals conviction. This isn't late-stage euphoria — it's early institutional accumulation confirming the macro bid.

Rotation logic: $BTC still leading means we're mid-cycle, not peak. Alts lag until $BTC consolidates. Stay flexible — ride $BTC strength, but watch for rotation signals when inflows plateau and dominance peaks.

Actionable: If you're underweight $BTC, this is your cue. Institutions are setting the pace. Don't wait for confirmation at $80K.
