Fidelity Defends Bitcoin Security Amid Halving Reward Concerns
Fidelity pushes back on fears that Bitcoin's shrinking block rewards erode network security after each halving event.

The asset manager's intervention signals that institutional voices are now actively shaping the narrative around Bitcoin's structural risks, not just its investment upside. Continue reading at Cointelegraph.
