On Sunday, June 13, 2021, Bitcoin ripped +9.8% to the upside to $39,021. Net flow: +4,430 BTC — buyers had the edge.
BTC price (blue) and trading volume (cyan bars) per minute. Session shading: Asia (gold 00-08 UTC), Europe (green 08-14), US (red 14-00).
The big players were active all day. 16 bars of outsized trades (7.9σ peak) from 00:49–22:45 UTC, adding 151 BTC of buying pressure on top of the broader buying flow.
A volatile day: 13.0% range from $34,757 to $39,380. Wide ranges like this create opportunities but also traps for directional traders.
Price followed flow faithfully (correlation: 0.99). When you see this level of alignment, it means one side is in control and the other isn't even fighting.
Cumulative buying pressure (purple, left axis) vs cumulative price return (yellow, right axis). When these diverge, flow and price are telling different stories.
Strip out US and the day would look flat. That session alone contributed 76% of the net flow (4,154 BTC buying).
Morning and afternoon traded like two different markets. Sellers led early (-150 BTC), buyers dominated late (+4,579 BTC).
Across sessions: Asia -0.75%, Europe +1.69%, US +8.75% — with US doing the heavy lifting.
