# MarketCap.com — Full Documentation

> MarketCap.com is a premium financial domain and live market data platform. It provides real-time data on cryptocurrencies, stocks, forex, and precious metals. The domain is available for acquisition.

## Overview

MarketCap.com displays live financial market data across multiple asset classes. "Market cap" (market capitalization) is one of the most important metrics in global finance, used daily to measure the value of public companies, cryptocurrencies, indexes, and entire financial markets. MarketCap.com represents the pure, generic form of that concept — a rare, category-defining digital asset.

## What Is Market Capitalization?

Market capitalization (market cap) is the total dollar value of a company's outstanding shares of stock, or the total value of a cryptocurrency's circulating supply. It is calculated as:

**Market Cap = Current Price × Total Shares Outstanding (or Circulating Supply)**

### Market Cap Categories for Stocks
| Category | Market Cap Range | Risk Profile |
|----------|-----------------|--------------|
| Mega-cap | $200B+ | Lower risk, stable |
| Large-cap | $10B – $200B | Moderate risk |
| Mid-cap | $2B – $10B | Higher growth potential |
| Small-cap | $300M – $2B | Higher risk, volatile |
| Micro-cap | Under $300M | Highest risk |

### Market Cap for Cryptocurrency
Crypto market cap uses the same formula: price per coin × circulating supply. Key related concepts:
- **Circulating supply**: Coins currently available in the market
- **Total supply**: All coins that exist including locked/vested
- **Fully diluted valuation (FDV)**: Price × maximum possible supply
- **Bitcoin dominance**: Bitcoin's market cap as a percentage of total crypto market cap
