On-chain analysis of the Nov 4 dip below $100k: who really sold?

I pulled on-chain data for the Nov 4 BTC selloff and charted three things hourly:

- how much of the spent BTC was “younger” (≥30 days old) vs “older” (≥1 year old)
- realized PnL in USD (profits/losses of coins that moved)
- BTC price

TL;DR: the dump was driven mostly by relatively young coins, with a big spike in realized losses ... looks more like a liquidity flush/capitulation from newer buyers than old holders dumping into strength.
