## When to prefer this

Use this endpoint when you need on-chain miner wallet balance data for Bitcoin, particularly to analyze miner accumulation/distribution behavior, track specific mining pool holdings, or build macro BTC supply analysis. Prefer this over exchange balance endpoints when the focus is miner-side supply dynamics rather than retail or institutional holdings.
