Bitcoin will never hit 21 million. Not because of lost keys or forgotten wallets. Because of something deeper. The actual supply is already ~179 BTC short... and shrinking. Here's why the "hard cap" isn't quite what you think 🧵 Miners Making Mistakes: Miners sometimes... just don't claim their rewards. Block 501,726: Miner solved the block, forgot to claim 12.5 BTC. Gone forever. Block 526,591: Claimed 6.25 instead of 12.5 BTC. Oops. In 2011, a miner named "midnightmagic" intentionally under-claimed by 1 satoshi as tribute to Satoshi. The smallest possible sacrifice. Total "under-claimed": ~29 BTC just... disappeared. The Genesis & The Bug: Then there's the stuff you can't spend even if you wanted to: • Block 0 (Genesis): Satoshi's first 50 BTC are hardcoded unspendable • The Overwrite Bug: Early code glitch erased 100 BTC in 2011 when two blocks got the same ID These aren't "lost" — they're provably destroyed. The blockchain knows they're gone. Running tally: ~179 BTC The Rounding Error: Finally: Bitcoin's math isn't quite 21 million. Because of how halving rounds down to whole satoshis, the theoretical max is actually: 20,999,999.9769 BTC Not 21,000,000. Subtract the ~179 BTC destroyed... True max supply: ~20,999,821 BTC So when someone says "21 million Bitcoin," remember: • It's already ~179 BTC short • The real cap is ~20,999,821 • And it's harder money than even the whitepaper promised Scarcity isn't just the design. It's the reality. Stack accordingly, villagers. 🏘️
