Fidelity Debunks Bitcoin Security Fears Amid Halving Cycle

Fidelity Digital Assets has pushed back against concerns that Bitcoin's long-term security will deteriorate as mining rewards decline. The company's research report argues that the network's economic incentives remain sufficient to secure the blockchain over time.

The report, authored by Daniel Gray, a Fidelity research analyst, suggests that transaction fees and market incentives continue to encourage miners to secure the network, making sustained attacks prohibitively expensive.

Gray pointed out that lower issuance has not translated into weaker incentives for miners because Bitcoin's rising price has more than offset the decline in block rewards. He noted that average daily miner revenue has increased substantially across halving cycles, from roughly $26,300 during Bitcoin's first halving cycle to over $40.2 million today.

The findings challenge a longstanding criticism that each quadrennial halving weakens Bitcoin's security by reducing the issuance of new coins. However, publicly traded mining companies continue to face near-term financial pressure due to lower mining rewards and rising costs.
