Bitcoin's security may weaken as miner rewards drop, risking network stability, warns Avalanche founder.

Emin Gün Sirer, founder of Avalanche, warns that Bitcoin could face long-term security risks due to declining miner rewards after each halving event. As block rewards shrink, miners may struggle to remain profitable, with up to 20% currently unprofitable, threatening the network's security. The debate focuses on whether transaction fees can compensate for lower rewards to keep miners incentivized. Sirer suggests technical changes like a pre-consensus layer might help, but such changes face resistance in the Bitcoin community, making the future security model uncertain.
