[Fidelity Refutes Claims That Halving Weakens Bitcoin's Security: Miners' Daily Revenue Has Increased from $26,300 to $40.2 Million] BlockBeats News, June 28: Fidelity Digital Assets recently released a research report directly addressing concerns that Bitcoin halving could weaken network security in the long term. The report's author, Fidelity research analyst Daniel Grey, pointed out that Bitcoin's network security does not rely solely on block rewards. Transaction fees, market incentives, and other economic forces also continuously motivate miners to maintain network security, making the cost of sustained attacks prohibitively high. From a data perspective, Grey noted that although block subsidies continue to decrease, the rise in Bitcoin's price has significantly offset this impact. Miners' average daily revenue has grown from approximately $26,300 during Bitcoin's first halving cycle to over $40.2 million today. He wrote: 'Despite the reduction in issuance, miner incentives—and the resulting network security—have historically strengthened alongside Bitcoin's price increases.' After the fourth halving in April 2024, miners' block subsidies will decrease from 6.25 BTC to 3.125 BTC per block. However, the report's optimistic outlook contrasts sharply with the challenging realities faced by publicly traded mining companies. Several industry analysts describe the current environment as one of the most difficult in recorded history, citing declining block rewards, rising operational costs, and intensified competition. In response, many mining companies have begun transitioning to AI and high-performance computing sectors, leveraging their existing power infrastructure to meet AI computing demands. VanEck estimates that publicly traded mining companies may need to raise up to $50 billion in additional funding to fully transition to AI infrastructure. However, the requirements for AI data centers—such as higher standards for facilities, cooling, power redundancy, and networking—are far more stringent than those of traditional Bitcoin mining farms, making the transition highly challenging.
