Definition. This chart presents the total ETH supply held by the Shark Cohort [Address Balance 100–1k ETH], and its 30-day net position change, alongside price. The traces are:

• 🟠 Total balance held by the Shark Cohort (line)
• 🟦 30-day net position change of Shark Balance (columns)

Technical. The cohort balance is the 100–1k ETH address balance band:

• Shark Supply = Supply(100-1k ETH)
• Net Position Change = diff(Shark Supply, 30)

This metric includes Externally Owned Addresses (EOAs) only (which includes exchanges, ETF products etc); smart contracts are excluded.

Interpretation. Sharks represent large private holders and smaller funds — capital sophisticated enough to act deliberately, yet less dominated by custodial structures than the whale bands. Sustained positive net position change in this cohort has historically been a constructive signal, indicating high-net-worth participants absorbing supply; sharp negative stretches flag distribution from this influential group. Band migration applies here too: an address growing beyond 1k ETH exits upward into the whale band, so pairing this chart with the whale cohort's balance helps distinguish selling from holdings simply outgrowing the band.

Notes. Built from Supply Held by Addresses with Balance 100–1k. The address count of the same cohort is charted in Shark Address Count; neighboring cohorts are Fish and Whale Net Position Change.
