Meanwhile, concerns grow over declining mining rewards and their impact on network security, as exemplified by Trump Media's significant losses from Bitcoin investments. --- ## Bitcoin Mining Pools Adopt Open Standards for Block Construction On May 11, seven of the largest Bitcoin mining pools, representing nearly 75% of the global Bitcoin hashrate, agreed to adopt the Stratum V2 protocol. This move is seen as the most significant decentralization shift in Bitcoin mining in recent years, allowing individual miners, rather than pool operators, to decide which transactions are included in new blocks. The pools involved include Foundry, AntPool, F2Pool, SpiderPool, MARA Pool, Block Inc, and DMND, which collectively control a substantial portion of the network's hashrate. The Stratum V2 protocol addresses long-standing concerns regarding centralized control over transaction selection. Currently, under the Stratum V1 standard, pool operators make these decisions, which has raised alarms within the Bitcoin community. The adoption of Stratum V2 is timely, as miners face challenging economic conditions, with estimates suggesting that around 20% are currently operating at a loss. The network difficulty is also set to increase, further complicating the mining landscape. > "This is the largest decentralization movement in Bitcoin mining in years," said a representative from the Stratum V2 working group. In summary, the adoption of Stratum V2 by major mining pools marks a pivotal moment in Bitcoin mining, potentially enhancing decentralization and addressing concerns over transaction selection. ## Concerns Over Bitcoin Mining's Future Amid Decreasing Rewards Emin Gün Sirer, the founder of Avalanche, has raised alarms about a potential existential crisis for Bitcoin mining due to declining mining rewards. In a recent statement, he emphasized that the long-term decrease in mining rewards poses a greater threat to the security of the Bitcoin network than the feared quantum computers. With the upcoming halving of the block subsidy in 2024, miners may increasingly rely on transaction fees, which could jeopardize the network's security. Currently, the block subsidy stands at 3.125 BTC, and the next halving is expected to occur in 2032, when the reward will fall below one Bitcoin per block for the first time. This shift could force miners to adapt their business models, raising concerns about the stability of the network. > "The incentive structure of Bitcoin mining could become problematic in the future," Sirer warned. In conclusion, the warnings from Sirer highlight the critical risks facing Bitcoin mining, particularly as rewards decrease and reliance on transaction fees increases, necessitating careful monitoring of the situation. ## Trump Media Faces Significant Losses from Bitcoin Investments The Trump Media & Technology Group reported a net loss of $405.9 million in the first quarter of 2026, with a substantial portion attributed to unrealized losses from Bitcoin purchases. The company's Bitcoin position alone has incurred losses of approximately $244 million, primarily due to acquisitions made near market highs in the summer of 2025. Currently, Trump Media holds 9,542 Bitcoin, with an average purchase price of $108,519 per BTC, while the current Bitcoin price is around $80,000. This situation underscores the inherent risks associated with cryptocurrency investments, as the significant drop in Bitcoin's value has led to considerable book value losses for the company. > "This situation illustrates the risks involved in cryptocurrency investments," an analyst noted. In summary, Trump Media's substantial losses from Bitcoin investments serve as a cautionary tale about the volatility and risks present in the cryptocurrency market.
