The Coinbase 50 Index (COIN50) is a regulated, market-cap-weighted benchmark tracking the top 50 digital assets on Coinbase Exchange. Excluding stablecoins and privacy coins, COIN50 focuses on rigorously vetted assets meeting fundamental and eligibility standards. Designed to capture the breadth of the cryptoeconomy, this index offers exposure to diverse sectors like DeFi, smart contracts, and Layer 1 blockchain platforms. Traders can engage through COIN50-PERP futures contracts, available on Coinbase Advanced (retail) and International Exchange (institutions), with up to 20x leverage. Rebalanced quarterly, COIN50 reduces concentration risk, providing a stable gauge for market trends. A strategic tool for investors seeking diversified crypto exposure, COIN50 mirrors traditional indices like the S&P 500 but applies crypto-specific criteria. Its transparent methodology, developed with Market Vector Indexes, supports informed decision-making for both experienced traders and new entrants navigating the volatile crypto landscape.
