Crypto market cap calculator: top assets, FDV, and Bitcoin vs Gold.

Market capitalization is the current token price multiplied by the circulating supply, meaning the tokens currently available for trading. Market cap is the total value the market assigns to all circulating tokens of an asset. It is the most common metric for ranking crypto assets by size, though it does not account for locked, staked, or unvested tokens that will enter circulation later.

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. That gap tells you how much dilution is still to come as locked tokens vest. The FDV/market cap ratio is a core 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 cached 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 places Bitcoin's cached market cap beside Sharpe's configured gold market-cap estimate and calculates the hypothetical BTC price and multiple if Bitcoin matched that value. It is a current-supply valuation scenario, not a forecast or a model of gold supply growth, liquidity, or future performance.

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, estimated ATH comparison mode, Bitcoin vs Gold, and stock/commodity/index comparisons are accessible immediately. Estimated ATH cap uses current circulating supply, not historical point-in-time supply.

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, so it amplifies gains in bull markets and losses in bear markets.

A stablecoin is a cryptocurrency designed to hold a stable value against a reference asset, most commonly the U.S. dollar. The largest stablecoins are USDT (Tether, ~$185B+), USDC (Circle, ~$75B+), and DAI (~$4B). Stablecoins are collateralized by fiat reserves, overcollateralized crypto (DAI), or algorithmic mechanisms. They are the primary medium for crypto trading pairs, DeFi collateral, cross-border transfers, and yield strategies. Stablecoin market cap growth is a common indicator of capital entering the crypto ecosystem.

Fully Diluted Valuation (FDV) is the current token price multiplied by max supply: the total value the project would have if every possible token were in circulation today. FDV matters most for low-float tokens. A project with $1B market cap at 10% circulating supply has a $10B FDV, so 9x more tokens can still enter circulation and create sell pressure. Tokens with FDV-to-market-cap ratios above 3-5x typically face sustained headwinds from vesting unlocks. FDV is more useful than market cap when 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 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 scenario is ETH's market cap exceeding BTC's, though the term is used for any ranking change. Sharpe's cached ranking table and calculator let you compare the two current market caps and compute the hypothetical target price; they do not forecast whether or when a flippening will occur.

The answer changes with Bitcoin and gold prices. Sharpe's tool compares the cached Bitcoin market cap with a gold estimate derived from configured above-ground supply and a gold price proxy, then shows the implied BTC price if Bitcoin matched gold's market cap. It does not show a historical ratio series or intermediate gold-share thresholds.
