20 Million Bitcoin Mined—Most Miners Won't See the Next One

The 20 millionth Bitcoin was mined this week — a milestone 16 years in the making — and it landed with a strange mix of celebration and dread inside the mining industry. Only 1 million BTC remain to be issued as block rewards. Getting there will take roughly 115 more years. And most of the companies mining Bitcoin today almost certainly won't be around to see it.

What Does the 20 Millionth Bitcoin Mined Actually Mean?

It means the supply clock is ticking louder. According to Wolfie Zhao, head of research at TheEnergyMag, the final 1 million BTC won't be fully mined until around 2140 — more than a century from now. That's not a typo. The Bitcoin protocol deliberately slows issuance over time through halvings, so while it took only 16 years to mine the first 20 million coins, the remaining supply will trickle out across the next century-plus.

Investors have known this since day one — Satoshi Nakamoto laid it out explicitly in the Bitcoin whitepaper, comparing Bitcoin's issuance schedule to gold miners expending resources to add gold to circulation. That analogy has since been adopted by everyone from BlackRock CEO Larry Fink to Strategy founder Michael Saylor to Federal Reserve Chairman Jerome Powell. The idea is that scarcity, like gold, underpins Bitcoin's value proposition long-term.

Why Are Bitcoin Miners Pivoting to AI?

The economics of mining have shifted dramatically since the last halving

Hash price — the revenue a miner earns per unit of computing power — has been stubbornly low. That's the brutal reality. John Todaro, a managing director and senior research analyst at Needham & Company, put it plainly: miners are operating at or near breakeven costs today, while net operating income margins in high-performance computing and AI are north of 80%. The math is not subtle.

Todaro said in a recent note that he expects a large portion of publicly traded Bitcoin miners pivot to AI — specifically, selling down nearly all of their BTC holdings before the end of 2026 to fund capital expenditures on AI workloads. Every single publicly traded miner his firm covers has already allocated some computing capacity to HPC or AI. This isn't a future trend. It's already happening.

"Stubbornly low hash price combined with the upcoming 2028 halving presents a concerning environment for Bitcoin mining operations," he told reporters. "Many operators are at or near breakeven costs today, while NOI margins in HPC are north of 80%."

Call it a strategic pivot, call it survival — either way, the mining industry's identity is fracturing.

Vertical Integration: The Survival Strategy for Bitcoin Mining

Bitdeer offers the clearest window into where this industry is headed. The Singapore-based miner is run by Jihan Wu — the same person who co-founded Bitmain in 2013 and once commanded roughly three-quarters of the global market for Bitcoin mining chips. Now Wu's company is converting facilities into AI data centers while simultaneously designing its own next-generation ASIC hardware.

Ross Gan, chief communications officer at Bitdeer, said the firm has Bitcoin's infrastructure in its DNA — but that DNA is evolving. "The miners that endure will be the ones that control more of the stack themselves," he said in a statement. "Vertical integration has proven to be one of the clearest markers of long-term survivability."

HIVE Digital Technologies — formerly HIVE Blockchain, founded in 2017 — got to this realization earlier than almost everyone else. Executive Chairman Frank Holmes was already talking up HPC infrastructure investments during an earnings call in November 2021, while the company was still generating revenue from Ethereum mining. The Ethereum merge didn't happen until a year later, in 2022, ending proof-of-work Ethereum mining entirely. HIVE had already seen it coming.

Holmes frames energy access as the real competitive moat. "Bitcoin miners have led the world in sourcing stranded and surplus energy and in building Tier I power infrastructure at scale," he said. "There is enormous energy abundance in the world, especially in hydro-rich regions like South America and Canada, but the winners will be operators that can secure it at low cost, structure around it intelligently, and turn that energy into durable computing infrastructure."

Does the 2028 Bitcoin Halving Spell the End for Smaller Miners?

The Bitcoin halving 2028 is already casting a shadow. After the next halving — forecast for mid-2028 — block rewards will drop again, tightening margins that are already razor-thin for operators without cheap power and efficient hardware. Todaro's prediction: many publicly traded miners exit Bitcoin mining entirely in 2027 and 2028 as they shift capital toward AI infrastructure.

Holmes, for his part, isn't ready to write the industry's obituary. He sees the approaching squeeze as a forcing function — not a death sentence. "Block rewards will decrease, but that does not mean the industry will disappear," he said. "It means the bar rises. The miners that survive will be the ones with the best power, the best sites, and the most flexibility."

VanEck's head of digital asset research, Matthew Sigel, made a bullish case on CNBC's Squawk Box — arguing that miners are uniquely positioned to benefit from the global scramble for electricity and computing capacity as AI demand accelerates. Miners were "aggressively diversifying" their capacity, he said, and had been underestimated in terms of upside. The energy infrastructure they've already built is the asset. Bitcoin just happens to be what they've been running on it.

So when block rewards eventually hit zero — in roughly 115 years — what happens to Bitcoin's price? Todaro thinks the effect will be muted. Most selling pressure comes from newly produced BTC, not long-term HODLers, he argues. And miners aren't even the largest holders anymore: all miners combined control just ~0.5% of circulating supply. Strategy, by comparison, holds 7x more BTC than every miner on earth combined. The era of the miner as Bitcoin's dominant market force is already over.

What's Left After 20 Million Bitcoin Are Mined?

A question worth sitting with: if miners are the ones who secure Bitcoin's network, and miners are leaving for AI, who secures Bitcoin in 2030? In 2040? The answer, presumably, is whoever still finds it profitable — operators with the cheapest energy, the most efficient hardware, and the deepest integration into the power infrastructure their data centers already occupy.

Foundry Digital announced on Wednesday it plans to offer a 20 millionth Bitcoin mined — specifically a mining pool for Zcash launching next month, aimed at publicly traded companies and financial institutions that lack the infrastructure to validate Zcash transactions independently. CEO Mike Colyer said Zcash has matured into a legitimate institutional asset. Whether that's a serious pivot or a hedge doesn't much matter — it shows that even the operators of Bitcoin's leading mining pool are keeping their options open.

The 20 millionth coin was a milestone. The next one — if and when it comes — will belong to an industry that looks nothing like today's.
