Everyone says bitcoin dumps at 10AM every day. I pulled the data, and it's not true. Since Jan 1, IBIT's cumulative return in the 10:00–10:30 window is +0.9%, and in the 10:00–10:15 window it's –1%. Noisy, not a systematic dump. More interesting: the performance pattern in both windows closely tracks the Nasdaq's. The "10AM dump" is just broad risk-asset repricing. The narrative is wrong.
