Crypto market cap calculator — top assets, FDV & Bitcoin vs Gold.

Market capitalization is calculated as the current token price multiplied by the circulating supply — the number of tokens that are currently available for trading. Market cap represents the total value that the market assigns to all circulating tokens of a given asset. It is the most widely used metric for ranking crypto assets by size, though it does not account for locked, staked, or unvested tokens that will enter circulation in the future.

Market cap uses circulating supply (tokens currently tradeable) while FDV (Fully Diluted Valuation) uses total supply (all tokens that will ever exist). For Bitcoin, these are nearly identical because most BTC has been mined. For newly launched tokens with vesting schedules, FDV can be 5-20x higher than market cap, signaling that substantial future dilution will occur as locked tokens vest. The FDV/market cap ratio is a key risk metric for evaluating token economics.

BTC dominance is Bitcoin's market capitalization divided by total crypto market capitalization. Sharpe's Market Cap tool focuses on live asset-to-asset valuation comparisons; use the Market Cap table and calculator to compare Bitcoin against other crypto assets, gold, stocks, or indices by absolute market value.

The seeded crypto rankings refresh from market data feeds under Sharpe's 30-minute page cache, with Supabase caches as fallback. Stock, commodity, and index references refresh through the Market Cap TradFi sync when the cache is older than 6 hours, with the previous successful cache preserved if an upstream provider is delayed.

The Bitcoin vs Gold comparison normalizes both assets by market cap, supply growth rate, and price performance to provide a direct comparison between the world's two leading store-of-value assets. Gold's total estimated market cap is approximately $16 trillion compared to Bitcoin's market cap. This comparison provides a widely used framework for Bitcoin's potential long-term valuation ceiling if it captures an increasing share of the store-of-value market.

The initial Market Cap table is seeded with the top 100 crypto assets plus configured TradFi assets. The calculator selector can search crypto assets on demand, so a long-tail token can still be added to a valuation comparison even when it is not in the initial top-100 table.

Yes. Market Cap rankings and the comparison calculator are available free on Sharpe Terminal with no account required. Top-100 rankings, FDV mode where available, ATH comparison mode, Bitcoin vs Gold, and stock/commodity/index comparisons are accessible immediately.

An altcoin (alternative coin) is any cryptocurrency other than Bitcoin. The term spans thousands of tokens including Ethereum, Solana, stablecoins, DeFi tokens, Layer 2 tokens, and memecoins. Altcoins collectively held roughly 40-50% of total crypto market cap through most of 2024-2025. The altcoin market is far more diverse than Bitcoin — some altcoins are smart contract platforms, others are governance tokens, utility tokens, or pure memes. Altcoin performance is generally higher beta than Bitcoin, amplifying gains in bull markets and losses in bear markets.

A stablecoin is a cryptocurrency designed to maintain a stable value relative to a reference asset, most commonly the U.S. dollar. Leading stablecoins include USDT (Tether, $140B+), USDC (Circle, $40B+), and DAI (MakerDAO, $5B+). Stablecoins are collateralized by fiat reserves, overcollateralized crypto (DAI), or algorithmic mechanisms. They serve as the primary medium for crypto trading pairs, DeFi collateral, cross-border transfers, and yield strategies. Stablecoin market cap growth is widely tracked as an indicator of capital entering the crypto ecosystem.

Fully Diluted Valuation (FDV) is calculated as current token price multiplied by max supply — the total value the project would have if every possible token were in circulation today. FDV is critical for evaluating low-float tokens: a project with $1B market cap at 10% circulating supply has a $10B FDV, meaning 9x more tokens will enter circulation and potentially create sell pressure. Tokens with FDV-to-market-cap ratios above 3-5x typically face sustained headwinds from vesting unlocks. FDV is more meaningful than market cap for comparing early-stage projects with different emission schedules.

Altcoin season indexes measure how many large-cap altcoins outperform Bitcoin over a trailing window. Sharpe's Market Cap product does not currently publish a standalone altcoin-season index; use the top-100 ranking table and head-to-head comparisons to inspect which assets are gaining or losing market-cap share.

The crypto fear and greed index is a composite 0-100 score that aggregates volatility, market momentum, social media sentiment, BTC dominance, and Google Trends data into a single sentiment reading. Values 0-25 indicate "extreme fear," 25-45 "fear," 45-55 "neutral," 55-75 "greed," and 75-100 "extreme greed." Contrarians use the index as a mean-reversion signal — extreme fear historically marks local bottoms within weeks, extreme greed marks local tops. The most widely cited version is published by Alternative.me.

Broad crypto directories are general-purpose asset catalogs. Sharpe's Market Cap is a focused comparison tool: top-100 rankings, if-X-had-Y valuation math, FDV and ATH comparison modes where data exists, Bitcoin vs Gold framing, and stock/commodity/index references in the same workflow. It is designed for relative valuation questions rather than exhaustive directory browsing.

A flippening is the event where one asset overtakes another by market cap. The most-discussed flippening scenario is ETH flipping BTC — ETH's market cap exceeding BTC's market cap — though the term is used more broadly for any ranking change (XRP vs USDT, SOL vs BNB, etc.). The ETH/BTC market cap ratio is the key metric; ETH needs to roughly 4x versus BTC to flip at current levels. Flippenings are important because they represent narrative inflection points — a flippening would fundamentally change how the crypto market views its dominant asset. Sharpe's rankings chart tracks these changes in real time.

Gold's total above-ground market cap is approximately $16 trillion (based on ~208,000 metric tons × ~$2,400/oz). Bitcoin's market cap at current prices is roughly 13–15% of gold's. For BTC to fully flip gold, BTC's price would need to rise roughly 7× from today. The comparison matters because gold is the dominant store-of-value asset and Bitcoin bulls argue for BTC to capture increasing share of the SoV market — a narrative that has driven institutional allocation and ETF demand since 2024. Sharpe's Bitcoin vs Gold tool tracks the ratio over time and shows the implied BTC price at various gold-share thresholds.
