The Final Million: Why Experts Say 20 Million BTC Mined Cements ‘Provable Scarcity’

The transition from a subsidy-based economy to a fee-based one remains the network’s greatest existential hurdle. Currently, transaction fees account for 2% to 5% of total miner revenue—a figure experts describe as mathematically insufficient to sustain the network’s multi-exahash security once the subsidy vanishes.

This revenue gap has sparked a contentious internal debate. Some developers have floated “anti-spam” proposals, such as those targeting Ordinals, to prune data-heavy transactions. However, critics like Minchi Park, co-founder and COO of Coinfello, view these efforts as economically dangerous.

“Regardless of whether you view Ordinals as a breakthrough or ‘rat poison squared,’ there is a compelling case for a permissionless ledger,” Park said. “Deeming certain satoshis ‘unspendable’ is shortsighted; we cannot predict which use cases the market will value in the future.”

While the experts caution against assuming this transition will happen automatically, there is a shared optimism that the evolution of wallet technology and the emergence of unforeseen use cases will create the necessary economic demand. Ultimately, the network’s long-term survival depends on whether it can foster enough utility to make its block space valuable enough to pay for its own protection.

Meanwhile, when asked if the 20-million-coin milestone will accelerate mergers and acquisitions within the mining sector, Beni noted that the event primarily exposes existing consolidation pressures. “Miners lacking structural cost advantages simply won’t survive the transition to fee-dependent revenue models,” he warned.

Park shared a similar outlook, suggesting that the upcoming halvings will serve as the ultimate litmus test for market participants. “As margins compress between halvings, it is reasonable to expect that operators burdened by high-cost energy or limited access to capital will either become acquisition targets or be forced to exit the market entirely,” Park said.
