The Vibe: The absolute maximum number of coins or tokens that will ever exist for a project — a hard-coded limit on future supply.
The Details: Max supply is the fixed cap written into a blockchain’s code (e.g., Bitcoin’s 21 million BTC, never to be exceeded). It creates scarcity: once reached, no more new coins are minted (beyond fees or rewards). Projects with max supply often become deflationary over time (lost coins reduce available supply). Compare to total supply (all created so far) and circulating supply (publicly tradable). Infinite or very high max supply can cause endless dilution. In 2026, Bitcoin’s cap remains the gold standard for scarcity.
Pro Tip: Always check max supply in tokenomics or on CoinMarketCap — capped supply is usually better for long-term holders (less inflation risk). Verify it’s truly hard-coded (not changeable by team).
