The Patoshi Pattern

Why it matters
It's the strongest on-chain evidence of how Satoshi actually behaved: restrained, considerate of other miners, and uninterested in cashing out. Those coins still haven't moved.
What it is
A fingerprint in the earliest blocks — an unusual way the ExtraNonce field was incremented — revealing that one miner dominated 2009–2010, deliberately capping at ~50% of the network. Researcher Sergio Lerner attributed it to Satoshi and estimated ~1.1 million BTC mined and never spent.
