The Bitcoin mining industry is undergoing a major transformation as it matures into a more institutionalized structure. Bitlease’s Nima Beni refuted concerns about the sustainability of transaction fees, stressing that current fee levels do not reflect long-term trends.
Challenging the security budget deficit
The transition of the Bitcoin mining industry to a mature institutional era has triggered a “systemic change” that fundamentally dismantles the traditional profit model. As block rewards gradually disappear towards 2140, the industry faces an existential crossroads. Miners must increasingly rely on transaction fees to fund their operations, which have traditionally been subsidized by newly minted coins.
This reality is captured in a recent report from Wintermute, which argues that the era of “underwriting hypergrowth” is over. As Bitcoin matures as a macro-risk asset, its volatility has diminished, breaking the four-year “halving cycle” that previously guaranteed exponential price increases. To survive this decline in profit margins, many industrial-scale miners are diversifying their revenue streams and repurposing their dense power infrastructure for high-performance computing (HPC) and artificial intelligence (AI).
Despite these pressures, some experts argue that the lack of a “security budget,” or concerns that transaction fees alone cannot maintain the network’s security, is often viewed through a narrow lens that ignores Bitcoin’s multi-decade timeline. The large subsidy is expected to continue over 40 years over the next 10 to 15 halving periods, and Bitlease founder Nima Beni argues that “treating current fee levels as indicative of a long-term structure misunderstands both timelines and market dynamics.”
Beni believes that the debate over the future of networks reveals deep contradictions. Many miners express concerns about future revenue while also supporting an ideological movement that opposes non-monetary use cases for blockchain.
“Bitcoin’s current fee market shows demand for block space beyond payment transactions,” Beni said. “That demand is actively suppressed by transit policies and social pressures that maintain a ‘pay-only’ ideology.”
According to Beni, the increase in inscriptions and ordinals proves that block space has “an important value that goes beyond payment.” He argues that as networks move from a subsidy-based model to a fee-based model, they become “more secure,” rather than less secure. When marginal and inefficient miners exit the market, the network’s difficulty adjustment allows remaining players to capture a higher percentage of fee income, maintaining Byzantine fault tolerance regardless of absolute hashrate levels.
Geographic optimization and grid integration
The Bitlease founder also argues that rising energy costs should not be seen as a threat, but rather as evidence of the Bitcoin network’s resilience against “jurisdictional capture.” Because capital and business are freely transferable, no single region can monopolize an industry through policy alone.
To illustrate this point, Beni highlights China’s decision in 2021 to effectively ban Bitcoin mining. Before the ban, Chinese miners controlled a disproportionate share of the world’s hashrate. However, rather than paralyzing the network, the ban triggered a mass migration of miners to more favorable jurisdictions. China lost its dominance as a Bitcoin mining center overnight.
For Beni, this episode highlights an important difference. While some miners rely on electricity demand to negotiate lower energy costs, the real survivors will be those willing to adapt and migrate if necessary.
“The miners who survive are not the ones who negotiate better retail rates,” Beni said. “These are miners who have migrated to areas where abundant energy creates a cost structure that competitors cannot match.”
Ultimately, this geographic optimization strengthens decentralization and ensures that the backbone of the Bitcoin network is anchored in the most efficient and politically diverse regions of the planet.
