TL;DR: Bitcoin mining pool competition has become increasingly concentrated since 2015, and newly awarded bitcoin is sent to different destinations, according to Chainalysis. The findings matter because concentration, routing, and control points can change how practitioners think about market resilience, custody, and abuse pathways.

Questions worth separating out
Q: How should organisations govern custody when mining rewards are routed through exchanges?
A: Organisations should treat mining reward routing as a controlled custody process, not a passive transfer.
Q: Why does mining pool concentration create governance risk for digital assets?
A: Mining pool concentration creates governance risk because a small number of operators can influence where value is sent and how quickly it moves.
Q: What breaks when custody and payout controls are not separated?
A: When custody and payout controls are not separated, the same account or role can both authorise and redirect value.
Practitioner guidance
- Map custody routing end to end Document every step from mining reward issuance to final exchange destination, including intermediate wallets, approvers, and account owners.
- Review concentration exposure in third-party risk Measure how much of your exposure depends on a small number of mining pools, exchanges, or wallet operators.
- Separate protocol trust from custody trust Do not assume blockchain integrity means operational integrity.

Market concentration in crypto infrastructure creates a governance problem before it becomes a security problem. When mining pools and exchanges become the dominant routing points for newly issued bitcoin, risk is no longer only about protocol integrity. It is also about custody concentration, decision bottlenecks, and the ability to audit value movement end to end. Practitioners should read concentration as a control issue, not just a market metric.
A question worth separating out:
Q: Which compliance controls matter most for mining-related bitcoin flows?
A: The most relevant controls are approval traceability, transaction monitoring, and documented accountability for wallet and exchange destination changes. In practice, compliance teams need evidence that value movements are authorised, reviewable, and linked to named owners. Where regulated entities are involved, those records should support audit, dispute resolution, and anti-fraud review.
