Show Notes
<p>In this episode of Sat Chats Short Stacks, Chris and Stewart try to crack one of Bitcoin’s greatest mysteries: Why did Satoshi choose 21 million? Is it math? Is it magic? Is it blackjack?</p>
<p>While there’s no official answer from the pseudonymous founder himself, Stewart walks us through the strongest theory yet—that 21 million was mathematically reverse-engineered based on block rewards, halving schedules, and Bitcoin’s 130-year issuance timeline. Of course, we also explore the fun stuff: slot machines, the 21st century, numerology, and yes, even 21 Savage. No stone left unstacked.</p>
<p>We cover:</p>
<p>✅ Why 21 million isn’t arbitrary</p>
<p>✅ How Bitcoin’s supply schedule shapes trust</p>
<p>✅ What halving intervals have to do with it</p>
<p>✅ Why the answer might be buried in math</p>
<p>✅ Theories from blackjack to divine numerology</p>
