Bitcoin's fixed 21 million cap underpins its scarcity narrative, but how many coins are truly in circulation? From lost keys and Satoshi's untouched wallet to quantum computing's potential to unlock them, the future of bitcoin's supply may surprise us.

Where are the coins?

This chart visualizes the distribution of bitcoin's 21 million supply. The largest portion, 57%, is held by individuals. "Lost" BTC, accounting for 17.6%, includes coins inaccessible due to forgotten keys (but will they stay lost forever?). Arguably, 5.2% of this total is associated with Satoshi Nakamoto's wallets. Since these coins have never moved, it's assumed that Satoshi either cannot or will not do so.

6.6% remains unmined, while corporations (excluding some miners) and bitcoin ETFs own 3.6% and 3.9%, respectively. Miners as a group retain 3.4% of the supply, and governments are holding 2.7%. Whether bitcoin's ownership is decentralized is an ongoing topic of debate, as is whether the shares of the pie locked or lost adds to its scarcity over the long term.

Lost coins may be never truly gone

For years, Bitcoin enthusiasts have clung to the narrative that some of its 21 million supply is irretrievably "lost," forever locked in wallets with forgotten keys. These "lost" coins have been viewed as a permanent reduction in the circulating supply, making bitcoin even scarcer than its fixed cap implies. But what if that scarcity isn't as definitive as we think?

The rise of quantum computing and breakthroughs in cryptographic techniques have sparked speculation that no bitcoin is truly "lost." As computational power evolves, the security underpinning bitcoin's oldest key pairs — generated using what may soon be outdated cryptography — could be compromised.

This isn't an immediate concern, as Bitcoin developers are well-equipped to implement protocol upgrades that shield active wallets. However, wallets abandoned long ago — like Satoshi Nakamoto's — and whose owners are unlikely to migrate them to new encryption schemes, could become targets.

Imagine quantum computing so advanced that "key miners" can derive private keys from public ones, effectively "cracking" these forgotten wallets. This would bring dormant bitcoin back into circulation — not through the intent of the original owners, but rather new actors exploiting advances on the periphery of technology.

Far from being FUD (fear, uncertainty and doubt), this idea reframes Bitcoin's evolution. The network's adaptability ensures it remains robust in a quantum future, but it also challenges the idea that its circulating supply will permanently exclude lost coins. As Nic Carter has noted, Bitcoin's security model doubles as a $400 billion "bug bounty" driving quantum advancements.

The treasure hunting of old wallets might one day become a competitive market, reshaping the narrative of bitcoin's scarcity. In this future, "lost" bitcoin doesn't stay lost — it merely waits for someone to unlock it, keeping the promise of 21 million circulating coins intact.

Whether that promise itself can be kept in the future is also an open question, but that's a topic for another day.

21 million can never be changed. Anyone who tells you it can….fundamentally does not understand how bitcoin works nor have they read any history.

Blackrock (524,571) and MSTR (423,650) collectively own almost 1 million bitcoin (out of 21 million) between just the two

BlackRock: "There is no guarantee that Bitcoin's 21 million supply cap will not be changed." 🤷‍♂️

I've been saying this for years: by stopping Bitcoin from scaling its L1, they've created the security budget issue which they're going to solve with additional emission 🪄
