Fidelity refutes claims that Bitcoin’s security declines post-halving, stating miners’ revenue increases as Bitcoin price rises.
According to Cointelegraph, Fidelity Digital Assets has rebutted concerns in a new research report that Bitcoin’s long-term security will deteriorate as mining rewards decline, asserting that the network’s economic incentives remain sufficient to secure the blockchain over the long term. Authored by Fidelity research analyst Daniel Gray, the report reiterates that Bitcoin’s security depends not only on block rewards but also on transaction fees and market-driven economic incentives, which will continue to motivate miners to protect the network—and render sustained attacks prohibitively costly.
The report challenges a longstanding critique that Bitcoin’s security is weakened every four years by the halving event, which reduces new coin issuance. It notes that since April 20, 2024, Bitcoin miners have received a subsidy of 3.125 BTC per block—down from 6.25 BTC in the previous halving cycle—but this reduction in issuance has not translated into diminished miner incentives, as Bitcoin’s price appreciation has more than offset the decline in block rewards. Gray points out that average daily miner revenue has surged from approximately $26,300 during Bitcoin’s first halving cycle to over $40.2 million today.
The report also notes that although Fidelity views the long-term incentive structure as sound, many publicly listed mining companies are currently facing financial pressure, with some diversifying into artificial intelligence and high-performance computing. VanEck recently
