Top 10 Cryptocurrencies — Frequently Asked Questions
## What does 'market capitalization' mean for a cryptocurrency?
Market cap is the current price of one coin multiplied by the number of coins in circulation. It is the most common way to rank cryptocurrencies by relative size, and it is the method used to order the list above.
## Why are stablecoins like Tether (USDT) and USDC in the top 10?
Stablecoins are pegged to a reference value (usually $1) and trade with very low volatility. Because of their huge circulating supply and constant price, they consistently rank among the largest assets by market cap, even though their price barely moves.
## How often is this list updated?
The list is regenerated from live market data, so each dated snapshot (for example, March 20, 2026) reflects the rankings at that point in time.
## What is a tokenized real-world asset?
A tokenized real-world asset is a blockchain token that represents ownership of an off-chain asset, such as a loan or a home-equity line of credit. Figure Heloc (FIGR_HELOC) is one example appearing in this snapshot.

Trend Analysis
Stablecoins—Tether and USDC—command the top 10 with near-perfect pegs, underscoring their role as market liquidity anchors. But the real story is the ascent of TRON, up 6.4% weekly, likely fueled by its dominance in USDT transfers and DeFi activity on the network. XRP's 2.9% weekly gain suggests lingering optimism around regulatory clarity. Dogecoin's 2.6% weekly drop confirms that without new catalysts, meme coins are falling out of favor. The surprise entrant, Figure Heloc (FIGR_HELOC), a token representing home equity loans, marks a tangible bridge between traditional finance and blockchain—a trend that could reshape the top 10 in the months ahead. Expect more real-world asset tokens to challenge the crypto-native incumbents.
